an important question for eating out is who
pays for the meal.if a friend of yours suggest（s） you
have lunch with him,you might simple（simply） say something
like this,"i'm afraid it'll have to be（go to） some place inexpensive
as i have very a（去掉） little money."the other person may say,"ok
i'll meet you at mcdonald's."this meal it is agree（d） that
two will go dutch,that is,each person pays for himself.
he may also say,"oh no,i want to take you for lunch at
johnson's",and"i want you to try the steak there.it's great."
this means the person intends to pay the bill for both of you.
if you receive this invention,you may say,"thank you.
