Thank you.Steven.That was the most magnificent meal I've had abroad.You ' ll have to let me reciprocate the next time you're in Beijing .   Don't worry about it , Lin.That ' s no big deal.You know , Americans appreciate China's rich culinary culture . Just excuse me for a second while I check the number here and figure out how much to give the waiter.Hmm , by the way , what do you do about tipping in China ?   We don't .   No tipping ? Now that's what I call a civilized system .   At hotels and some restaurants they add a service charge to the bill , but other than that , tipping isn't customary .
