I can live with most of these.

#3 Nope, not in Russia.

#17 like in other parts of the world, you don't go prowling through someone's fridge when you're invited.

#20 Not in France. Well it is gross everywhere, but that will shock no one if you decide to empty your nostrils into a tissue.

#22 Yeah no, Russia again. It's considered impolite to not finish your plate.

#3 South America where? far as I know in Brazil it is not. Unless ur face clearly show sarcasm.

#2 Bullshit. I've never heard this rubbish in Oz, and I've caught many taxis.

#14 if someone had to pay for a drink and you take it, it is just stealing that's rude everywhere. In Norway beer is just extraordinary expensive.

#5 saying that you can't have a country with the same name as the continent on which it resides is just plain stupid. You can't have a country called the United States of America on the continent of North America? And people in South America think they are Americans because the name of the continent has "America" in it but their country doesn't? F*ck them.
