If you’re wondering why some of these rules apply here are more detailed descriptions:
France: It’s rude to ask about money pretty much anywhere, but especially in France.
New Zealand: Honking is an insult of one’s driving ability taken rather seriously.
Japan: The Japanese take pride in providing the very best service sans tips.
Norway: Many locals don’t attend church and consider related questioning rude.
UK: Asking someone how much they earn can make them feel uncomfortable no matter where you are.
Germany: Local superstitions believe if you are congratulated prematurely for a birthday you might not live to see the actual date.
Chile: Eating with your hands is considered rude and manners matter here.
USA: Tips are a must; they are what service-based workers rely on to pay the bills.
Hungary: Clinking glasses is an old habit, but one that is largely avoided in Hungary, especially in regards to beer.
Ukraine: In Ukraine and most Slavic countries people bring an even number of flowers to the cemetery.
India: PDA, such as hand holding and kissing, is considered highly inappropriate and forbidden in public.
Mexico: Locals like to make jokes that are lighthearted and fun, so don’t take anything too seriously.
Turkey: The sign for ‘OK’ is an inappropriate gesture in Turkey that means something much different than ‘OK.’
Ireland: Locals don’t think they have an accent, so why confuse them?
Kenya: Calling someone by their first name is only acceptable after they call you by your first name.
Singapore: Eating on public transportation is gross just admit it. In Singapore you should also avoid feeding the birds, throwing garbage or spitting in the street.
Italy: You can order a cappuccino at lunch or dinner but only if you want to stand out. Italians only drink cappuccinos for breakfast.
China: Clocks and umbrellas are seen as bad luck when given as a present.
