Korea is the only country I've been to so far where someone wearing glasses in an advert isn't necessarily a nerd or advertising an optician. Koreans can also pull off white-framed glasses.
Chivalry died in Korea. Or was never born here. You stand up for an old lady on the bus and some guy takes your seat.
People stand right by the door on the subway, even when they're not getting off and there's plenty of room on the rest of the carriage.
It's rude to blow your nose here but not to hock up a load of spit and hurl it out.
Men fart loudly and unashamedly all the time. Sometimes, it's as if they wait for you to walk past before letting rip.
Seat-switching on buses. I watched one guy change seats five times in a ten-minute bus journey. Also, the other day, the bus driver stopped the bus and removed a giant bee for the screaming passengers. I wasn't screaming, I just moved seats. Oh no! I'm a seat-switcher!
Bus drivers here are mental.
People watch TV on their phones all the time. We were having dinner in a little place near us the other night and a woman came in with her sons and ate one-handed, watching her phone TV the whole time. You mainly see it on public transport because all you can do is sit there. But then they walk off still watching it and somehow avoid bumping into people. Having said that....
....people bash into you all the time. Mainly old women and old men.
An alarmingly large proportion of middle-aged women wear visors.
