5. Never let someone else pay the bill without fighting for it

In the past, I was stunned the first time I witnessed the many fairly chaotic, noisy scenes at the end of a Chinese restaurant meal. The time to pay the bill has come and everyone is simply doing what they're expected to do — fight to be the one to pay it. The Chinese consider it good manners to vociferously and strenuously attempt to wrest the bill out of the very hands of whoever happens to have it. This may go on, back and forth, for a good few minutes, until someone "wins" and pays the bill. The gesture of being eager and willing to pay is always appreciated.
