I found an article giving a guide to American's when they are going abroard:
Tips for travellers: This month, San Francisco-based BDA - whose board includes executives from **** and McDonalds - began distributing a World Citizens Guide to corporate travellers. Its 16 points are a mirror image of the behavioural patterns that earned Americans a boorish reputation in the first place. Heres a sampler from the guide.
* Think as big as you like but talk and act smaller. In many countries, any form of boasting is considered rude. Talking about wealth, power or status - corporate or personal - can create resentment.
* Speak lower and slower. In conversation, match your voice level and tonality to the environment and other people. A loud voice is often perceived as bragging. A fast talker can be seen as aggressive and threatening
* Dress up. You can always dress down. In some countries, casual dress is a sign of disrespect. Check out what is expected and when in doubt, err on the side of the more formal and less casual attire. You can remove a jacket and tie if you are overdressed. But you cant make up for being too casual.
* Listen at least as much as you talk. By all means, talk about America and your life in the country. But also ask people youre visiting about themselves and their way of life. Listen, and show your interest in how they compare their experiences to yours.

I think all that this article says about American's is generally true... but I know that not all of you guys are like that at all

P.S: Sorry if I offended any of you Americans. You got to agree that Bush is an idiot (as is Blair here in England)
