Observations from Seoul

Things you should know about Korea:

1) They have law against littering, but spitting on the street is not an offense -_-. You see the elderly especially, spitting on the street still.

2) You have to separate your litter and place them in the prepared bins accordingly - normal trash (i.e. tissue paper, paper boxes, perishables), bottles & cans, and plastics. At the subway stations, there are bins for recyclable and non-recyclable waste.

3) Stand on the right of escalator to give way. Otherwise, you will have screaming ahjummas (elder woman) yelling gibberish words at you.

4) Similar to Taiwan, you're supposed to throw used toilet papers in the bin next to the toilet bowl, not INTO the toilet bowl. I still find it hard accepting this as it makes the toilet smell.

5) You can get bloody cheap socks in Korea (1000₩ per pair)

6) You can eat/drink at the subway station. They even have F&B kiosk at the platform.

7) There's free wi-fi at subway stations (even at the underground platform).

8) When you dine out, some stalls do not allow sharing. If there's two of you, you need to place order for two.

9) Some of the middle-aged and elderly can really be rude. They talked loudly and scold each other on the street even. Note that they are strangers. If you need help in Korea, approach Gen-X or Gen-Y, NOT the baby boomers. And please do not expect 'Excuse Me' or 'Sorry' when someone knocks into you on the street, in subways, in fact, not anywhere. The ahjummas will push you as they like, if you are blocking the way or if they deem you walking too slow for their liking.
