An important question about eating outside is who pays for the meal. If a friend of yours asks you to have lunch with him, you may say something like this, “I’m afraid of it,I’ll have to be some place cheap, because I have very little money .”The other person may say, “ OK, I’ll meet you at McDonald’s.” This means that these two persons agree to “go Dutch”, that is, each person pays for himself. He may also say, “Oh, no. I want to take you to lunch at Smith’s,” or “I want you to try the Chinese dumplings there. They’re great.” This means the person wants to pay for both of you. If you feel friendly towards this person, you can go with him and you needn’t pay for the meal. You may just say, “Thank you.” That would be very nice.

American customs（风俗） about who pays for dates（约会） are much the same as in other parts of the world. In the old days, American women wanted men to pay for all the meals. But, today, a university girl or a woman in business  world will usually pay her way during the day. If a man asks her for a dance outside the working hours, it means  “Come, as my guest（客人）.” So as you can see, it is a polite thing to make the question clear at the very beginning
