I am ripping off SFGate here, but it's precious:
Travel Tips for those behaviourally challenged when abroad
Although I am a little confused as to why you can't have your hands in your pockets in Russia. I've never observed that to be a huge problem. But overall, Russians don't put hands in pockets unless it's January and you lost your mittens.
My favourite thing on the list is:
"In Uruguay, don't tell people you're enjoying your stay in Paraguay. (Similar rules apply for Sweden and Switzerland, Slovakia and Slovenia, Niger and Nigeria, Macedonia and Mesopotamia.)"
Also, it should also be added "Never, in any country, wear shorts, white trainers, and a fanny pack..."
Do any of you have travel tips?
