#Person1#: Will you bring our bill, please?
#Person2#: Yes, certainly. I'll be back in a minute. Here you are
#Person1#: Thanks. Let me see. I think there's a mistake on the bill here. Would you mind checking, please?
#Person2#: Of course, not. Let me check. Oh, you seem to be correct.
#Person1#: How about tax and service charge?
#Person2#: Only ten percent tax is included in the bill.
#Person1#: Then one hundred U. S. dollars covers everything, doesn't it?
#Person2#: It sure does.
#Person1# finds the bill mistaken. The bill is one hundred U. S. dollars in total.
