I guess, based on this thread, that its wrong of me but.....

However, being born and raised outside the US, i tip 10% only on extremely good service. I am born in Asia and raised in Europe. In fact, this thread really makes me regret moving to the US in the first place. But come on, the globe is bigger the the US..It is a matter of raising above what the US thinks, wants and means..

Tipping is only when deserved. Just like when someone asks you "how are you you doing" is for when you REALLY mean it. The diversity of this country leaves this kind of pointlessness to only when you mean it. Otherwise its pointless to ask, just ask any banker that is told to ask this, and when you respond with anything but " fine thank you, and how are you" they look at you like you are an alien..

Try visit any Asian country, and then I do not mean a Asian dinner in the US. They do not ask you UNLESS they actually mean it. Not some fake standard wannabe customer issued statement like here.
