Reddit Says Vs What I’ve Seen In 24 Years: Seven Korea Myths Checked

Several popular Korea travel myths are out of date. Public restrooms have asked you to flush toilet paper since 2018. There is no official “stand right, walk left” rule, and since September 2026 the official advice is not to walk at all. Leftovers to go are normal at many restaurants, and Seoul has plenty of free toilets. Two claims hold up: physical T-money top ups still need cash, and queues depend on the place.

This is the first in a series. I take the advice travellers repeat online, check it against official sources, and tell you what I’d do. For the full set of habits, start with my unwritten rules of Korea.

Sunbae Says: If a tip online is older than your phone, check it. Korea changes its rules faster than forums update.

How This Works

For each myth you get three parts. What travellers say is the claim as it usually appears in forum threads. What’s actually true is the verified position, with a link to the source. My take is my opinion after 24 years here, or a field test placeholder where I want a fresh result before I tell you.

Myth 1: Put Your Toilet Paper In The Bin

What travellers say: Korean plumbing can’t handle paper, so put used toilet paper in the bin next to the toilet.

What’s actually true: The rule changed on 1 January 2018. A revised Public Toilets Act removed bins from public restroom stalls, with special boxes for sanitary products in women’s stalls and fast dissolving paper instead, as The Korea Herald reported when the Cabinet approved it. Facilities that ignore it face fines of up to 1 million won, but a 2019 follow up noted the government can’t force private buildings to remove their bins.

My take: In a subway station, a department store or a public park restroom, flush. In an older private building, follow the sign on the wall. Wet wipes never go in the toilet, anywhere. My toilets, trash and recycling guide has the rest.

Verdict: Outdated for public restrooms.

Myth 2: Stand Right, Walk Left Is The Rule

What travellers say: On escalators, stand on the right and walk on the left, like London.

What’s actually true: There’s no side rule, and now there’s official advice against walking. The government promoted one side standing from 1998, switched to a “two lines” campaign from 2009 to 2014, then stopped recommending either in 2015. In August 2026 a government survey of 1,000 adults split 50.1% for one side standing and 49.9% for two lines, The Korea Herald reported. On 23 September 2026 the Ministry of the Interior and Safety settled it with three safety rules: hold the handrail, don’t walk or run, and stay behind the safety line, per Seoul Economic Daily.

My take: In Seoul you’ll still see many people stand right and leave the left open. Match the people ahead of you, but never push past or lecture anyone standing on the left; they’re following the official advice. It’s a safety campaign, not a law, so nobody will fine you. More in my Seoul subway etiquette guide.

Verdict: A habit, not a rule. Officially, don’t walk.

Myth 3: T-Money Only Reloads With Cash

What travellers say: You can only top up a T-money card with cash, so always carry won.

What’s actually true: Still true for the physical card at stations. Since 17 March 2026, the new ticket machines on Seoul Metro Lines 1 to 8 accept foreign issued cards, but Money Today reported (in Korean) that this covers single journey tickets and the 1, 2, 3, 5 and 7 day short term passes only, not T-money top ups. The 30 day Climate Card ended on 1 October 2026; the short passes continue.

My take: Keep 10,000 to 20,000 won in cash for top ups. If you’ll ride a lot, a short term pass bought by card at those machines sidesteps the problem. My tourist transit card guide does the maths, and my money guide covers cards and cash.

Heads Up: Plenty of 2024 and 2025 posts still tell you to buy the 30 day Climate Card. It’s gone. Seoul ended it on 1 October 2026, and only the 1 to 7 day passes remain.

[SUNBAE FIELD TEST: try topping up a physical T-money card with a foreign Visa or Mastercard at a new Line 1 to 8 station machine and at a CU or GS25 counter; report whether either accepted it, what the screen or staff said, and any fee]

Verdict: Still true for T-money; not true for the short passes.

Myth 4: Taking Leftovers Home Is Rude

What travellers say: Asking for a doggy bag in Korea is embarrassing.

What’s actually true: There’s no rule against it. What is regulated is the restaurant side. The food ministry tightened its ban on reusing customers’ leftovers in 2018, starting with buffets, with penalties of up to a 15 day suspension, The Korea Times reported. It’s taken seriously: stalls caught reselling leftover side dishes at Gwangjang Market made national news in 2026, Hankyung reported (in Korean). What you leave is meant to be thrown away.

My take: At a normal restaurant, pointing at the dish and saying 포장해 주세요 (pojanghae juseyo, “please wrap this”) is normal in my experience, and staff will often bring a container. Buffets are the exception: don’t pack food from a buffet. How to ask for things politely is in how to order in Korea.

Verdict: Myth, with a buffet exception.

Myth 5: There Are Hardly Any Public Toilets

What travellers say: Finding a toilet in Korea is a nightmare.

What’s actually true: Visit Seoul says the city has plenty of clean, modern public restrooms, most of them free, and the vast majority Western style. The city also pays private building owners to open their restrooms to the public. Cleanliness is a fairer complaint: when Busan interviewed 34 foreign visitors in August 2026, cleanliness topped the list at 25%, with Japanese visitors singling out restrooms and drain smells, Seoul Shinmun reported (in Korean).

Option	Best For	Cost	Time	My Take
Subway station restroom	Anywhere in the city	Free	Usually under 5 minutes away	My default. Check whether it’s inside or outside the gates before you tap.
Department store or mall	Families, the cleanest stalls	Free	Depends on the area	My pick with kids.
Open restrooms in private buildings	Lanes away from stations	Free	Look for the sign	Handy, but quality varies.
Café	Desperate moments	A drink	Instant	Buy something first; some lock the door with a code.

My take: Subway stations are my default. Carry tissues for the odd stall that’s run out.

Verdict: Myth, at least in Seoul. Cleanliness varies.

Myth 6: Koreans Don’t Queue

What travellers say: People push in, so be ready to elbow.

What’s actually true: It depends where you are. At popular restaurants, queues are often digital: CatchTable runs reservations and remote waitlists, and VisitKorea notes its global version lets you sign up through Google or Apple with no Korean phone number, in English, Japanese and Chinese. Beyond that, what follows is my read, not data.

My take: Queues are strict at bakeries, terminal bus stops and waitlisted restaurants. They’re looser at lift doors and at subway doors in rush hour, where the crowd moves as a block. It’s density and speed, not rudeness, a point I make in why Koreans seem rude (and aren’t). Line up where you see a line; hold your ground politely where you don’t. My travel apps guide covers the waitlist setup.

Verdict: Half true. Depends on the place.

Myth 7: GTX Is Relaxed About Priority Seats

What travellers say: On the new GTX express trains, nobody minds who sits where.

What’s actually true: GTX-A (purple), the deep express line, opened on 30 March 2024 between Suseo and Dongtan, a 21 minute ride, Seoul’s news hub reported (in Korean). A northern section runs from Unjeong in Paju to Seoul Station, but the middle link through Samseong has been delayed by a construction defect at the Samseong transfer centre; in June 2026 the transport ministry said it would need at least four more months of checks and test runs, Newspim reported (in Korean). I could not find an official statement on how priority seating works on GTX trains, so this one needs eyes on the train.

My take: Until the test below is in, treat any marked priority or pregnancy seat on GTX exactly as you would on the subway: leave it for someone who needs it.

Heads Up: Don’t plan a trip around a through GTX-A ride from Seoul Station to Gangnam or Suseo. As of early October 2026 the Samseong section’s opening date was still unconfirmed. Check Naver Map on the day.

[SUNBAE FIELD TEST: ride GTX-A at a busy and a quiet time and check whether cars have marked priority or pregnancy seats, where they are and how passengers use them]

Verdict: Unconfirmed. Test pending.

What Locals Know

The bins weren’t about weak pipes alone. The government’s case in 2017 was hygiene: open bins of used paper smelled and spread germs, so it switched public restrooms to fast dissolving paper. A government survey found 81% support, though cleaners told the Herald some people still leave used paper on shelves. Old habits are why you’ll still see the occasional bin.

The escalator rule is about older riders. The Herald’s figures show 72.3% of escalator accidents from 1993 to 2025 were down to how people used them, and people aged 60 and over were 53.3% of those hurt. That’s why the ministry chose “don’t walk” over picking a side. Think of the ajumma and ajeossi behind you.

Korean media fact check this stuff too. The Gwangjang leftovers story, the escalator forum and the tourist payment complaints were all covered in depth by Korean language news. When an English forum thread and a recent Korean headline disagree, check the date: the forum post is often years older.

What’s Changing In 2026

The rules are live topics. The escalator question was settled in September 2026, foreign cards reached Seoul subway ticket machines in March, the 30 day Climate Card ended on 1 October, and Seoul buses are due to accept foreign tap to pay cards from 2027. This list will need updating, which is why it’s a series.

More visitors means more outdated advice. Record numbers of first timers are reading older threads. When a tip conflicts with a sign in front of you, trust the sign, and when there’s no sign, fall back on the unwritten rules.

Pick Your Version

If It’s Your First Time. Remember three corrections: flush in public restrooms, carry cash for T-money or buy a short pass by card, and stand still on escalators. The first timer hub covers the rest, and my twelve small surprises covers the quirks that are real.

If You’re Bringing Kids. Department store restrooms are your friend; I’d do a toilet stop before every tap out. Pack a small container if your kids leave half their dinner.

If You’re Travelling Solo. Waitlist apps are made for you. I’d join a remote waitlist and explore nearby instead of standing in the queue.

Sunbae’s Picks

The myth I’d drop first: the toilet paper bin. It causes more awkward moments than any other.

The myth I’d keep: carry cash for T-money. It’s still the safest plan.

I’d skip arguing about escalators with anyone. Hold the rail and enjoy the ride.

Offers Worth Knowing

Seoul’s short term passes (1, 2, 3, 5 and 7 days, up to 20,000 won for 7 days) cover unlimited Seoul subway and city bus rides, and you can buy them by foreign card at the new Line 1 to 8 machines.

[AFFILIATE: Klook or Trazy WOWPASS pickup]

Worth It / Skip It

Worth It: checking the date on any Korea tip before you rely on it.

Skip It: the “elbow your way in” advice. Watch the queue; there usually is one.

Word Of The Stop

줄 서다 (jul seoda): to line up. You’ll hear 줄 서세요 (jul seoseyo), “please line up”, at popular spots.

Frequently Asked Questions

Can You Flush Toilet Paper In Korea?

In public restrooms, yes, since a 2018 rule change removed bins from stalls. Older private buildings may still ask you to use a bin; follow the sign.

Do You Stand On The Right In Korea?

Many people do in Seoul, but it isn’t a rule. Since September 2026 the official advice is to hold the handrail, not walk or run, and stay behind the safety line.

Can I Top Up T-Money With A Credit Card?

Not a physical T-money card at station machines. Foreign cards work there for single tickets and short term passes. Bring cash for T-money.

Is It Rude To Ask For Leftovers In Korea?

No. At most restaurants you can ask 포장해 주세요. Don’t take food from buffets.

How I Checked This

On 5 Oct 2026 I rechecked the toilet bin rule in The Korea Herald’s 2017 and 2019 reports, escalator history and the September decision in The Korea Herald and Seoul Economic Daily, the ticket machine change in Money Today, the Climate Card change on Seoul’s FAQ, the leftover rule in The Korea Times and Hankyung, toilets on Visit Seoul and in Seoul Shinmun, CatchTable on VisitKorea, and GTX-A’s status on Seoul’s news hub and in Newspim. Still unconfirmed: whether T-money can be topped up by foreign card anywhere in person, how GTX priority seats are marked, and when the Samseong section opens.
