    B : 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.(Examines the bill) Hmm, by the way, what do you do about tipping in China?
    A : We don't .
    B : No tipping? Now that's what I call a civilized system.
    A : At hotels and some restaurants they add a service charge to the bill, but other than that , tipping isn't customary.
    B : What about cab drivers and porters?
