Complete Idiot's Guide to Cultural Etiquette

This is a really interesting book, as it contains cultural information for many places around the world, which you may even find useful for your contacts and trips. However: 1) It is addressed mainly to US citizens and their specific cultural background, and 2) Contains some errors (at least some I could notice about the Greek and the Japanese cultures). So, please enjoy the book, but do not take it as a textbook... Anyway, if I would ever wanted to conduct serious business with an Indonesian (and not a one-time contact), I would spend much more time on investigating cultural issues :)
