If you have agreed to go out to eat with someone，you should be clear who is paying．If the other person suggests that you should have lunch with him or her，you might simply say something like this：“l’m afraid it’11 have to be some inexpensive place as I have very little money．”The other person may say：“0．K．I’11 meet you at McDonald’s．”This means that it is agreed that each person pays for his own meal．If the person says“Oh，no，1 want to take you to lunch in a little restaurant I like very much．”it means that the person wants to pay the bill(账单)for both of you．If a person invites you to his or her home for a meal，it is understood that that person is paying；if you invite someone to your home，it is，understood that you are buying the food．If you want to invite someone out for lunch，you must also make yourself clear that you are paying by saying，for example，“Let’s have lunch together tomorrow at Burget King．It’s on me．”American women used to expect men to pay for all meals，but today most women will pay for themselves． 回答问题
