Do sales girl have the bargain over everything?

Dialog Exerciese

As the French thinker and essayist Michelle de Montaigne wrote, “Marriage may be compared to a cage: the birds outside despair to get in and those within despair to get out.” See the pair of birds:
Luke: Lily, see we have known each other for three years.
Lily: Yeah, how time flies!
Luke: Well, have you ever thought of ending this kind of relationship?
Lily: What do you mean? You have someone on the side?(女孩吃错的表现，是不是外面有人了^_^)
Luke: I mean, marry me!
Lily: I love you, but I don't want a kid. I don't feel like taking care of kids.
Luke: My mother will.
Lily: I cannot get on well with your mother. I don't want to live with her.
Luke: Do sales girls have the bargain over everything?


Do sales girls have the bargain over everything?是不是女店员每件事都要讨价还价呢？
