What not to do in countries around the world

Don't tip their waiters because it's considered rude.

Don't nod your head up-down if you want to say 'yes'.

Don't split the bill! It's considered unsophisticated and we don't like to talk about money.

Don't jump the queue! "Queue jump — this is the only crime that the population would consider bringing back capital punishment for."

Don’t use your left hand to greet someone, exchange money, or pick up merchandise!

Don’t be impatient! (Hardly anything runs on time, with an exception of a couple of business meetings and bank closing hours and most other businesses. Everything runs late, don't get pissed off or impatient, learn to go with the flow, things will happen, just not on time.)

Don’t smile at strangers! (They’ll see it as an intimate gesture, indicating a genuine affinity toward another person. If you don’t know them, they might consider you insincere.)

Don't feed the birds! (Feeding the birds, littering anywhere, and chewing gum in public will land you with some high fines.)

Don’t wave at people in the street! (Showing your palm to others means rejecting them.)

Don't walk in the bike lanes!
