Prot Tip "Asia" (sure in Japan not sure in the rest of it): Don't stick your chopsticks directly in the rice leaving in there stuck upwords (like, if you have to drink and want to free your hand) as it resembles offerings to the dead during mourning periods and it's considered rude/bad luck People won't really mind, but it's a small thing to remember just in case. It shows respect.

actual tips from actual african: do not point at PEOPLE. do not click your fingers, especially at people. Do not make and hold eye contact, rather look down. You can talk during a meal. Hand is not an issue if you are using a knife and fork like a westerner. Maybe hand issue applies outside of south africa. Most important thing actually is to acknowledge other people and ask after their health, and wait for an answer, and interact with the answer. IE do not just say "give me 5 packs of cigarettes" or whatever. Start with greetings and health questions. Queue if possible. If others are not queuing, you don't have to. ALWAYS tip generously.

"Greet shopkeepers and say goodbye" - this should be common sense everywhere. Same with bus/ taxi drivers, museum staff etc.

In Spain you have to wait for WHAT??? I must say that all the siesta thing is A LIE!! Like all the rest of the world thinks we stop the entire country only to have A NAP?? WTF?? My dudes that's totally wrong, we close at 2pm most shops for lunch breaks and sometimes (mostly in summer because of the heat and having way more hours of sunlight.) some restaurants will stay closed from 3pm until 8pm or so, and that would apply for most places because you don't want to have a heat stroke working, so we open later. It's more a weather thing, not that we simply go back home to have a nap....

Having cared for many Chinese patients and their families, we were given to understand that when you are conversing, do not look them directly in the eyes. It’s considered very rude. As far as South America and arriving a little late, my nephew is married into a family from a South American country that shall go unnamed. Try 2-3 hours. At some point when I visit I will be meeting his wife’s family at a gathering. I’m going to need to duct tape my mouth as I am a very punctual person and consider that kind of late to be disrespectful. But, then again, just roll with the cultural norms because they are such laid back folks. I could probably learn something about how to live your life with less stressing out.

The "siesta"' thing applies for Greece too. Although it's not that everything stops at some point during the day so people can go have a nap. It's directly connected to the weather conditions in these countries( can be really hot in the summer during specific hours of the day) and as time went by it's become a thing in their culture. Like many many things in other countries that are affeliated with the climate

Can only speak for Japan, South Korea & Taiwan but many cafes & restaurants will offer knives, forks & spoons or provide them on request - most will do so in tourist areas

It's interesting to see people from various countries commenting offended by the stereotypes listed here and no one really does that, or saying that the thing listed is completely natural so of course everyone always does that. The cool thing with this big world is that many different things are normal in different places. I feel privileged to learn about practices that are outside of my experiences so far!

Respect personal space also in many parts of Europe

Im a lefty sooo Arabic is out for me

Lol, here the ok gesture means something like "go f**k your self", it can mean other stuff as well but mostly vulgar as the circular shape is either as a reference to a**s or vagina.

When traveling in China and Hong Kong, the bellhop and staff bringing in room services always stood in the room waiting for a tip. When getting a foot massage in HK, the shop owner wouldn't let these 2 women leave until they tipped their masseuses in cash. In China, I was prohibited from giving the girl (who gave me the best foot and should massage of my life) a tip. My friend, who is a local, said the girl could get fired for accepting a tip.

The unclean left hand ones suck for me, because I'm left handed

Asia: avoid body contact. (Google: subway pushers of Japan...)

No siesta in Portugal. Restaurants might close between meals for the staff to rest, though. But everything else is open all the time.

Cover up in more conservative countries, it will avoid attracting attention
