M: How can I help you?
W: I would like to open a new savings account, please.
M: You need to deposit ＄100 to open your account.
W: But I called last week and was told it was ＄ 50.
M: I’m sorry, but we’ve changed our policy.
W: You mean if I’d come last week, I could have opened an account and today I can’t!
M: That’s right. I’m very sorry.
W: I want to see the person in charge.
M: You’re speaking to him.
W: In that case, I guess I’ll have to go someplace else with my business.
M: Now don’t be hasty. Maybe we can work something out. After all, every person who walks in here is a valued customer. Tell me, are you a student by any chance?
W: Yes, I’m enrolled at the university.
M: Why don’t you say that before! There’s no problem then. Our minimum amount for opening a student account is ＄50.
W: Well, that’s fine, but now I don’t know if I want to open an account here.
M: We’ll give you a free backpack. It’s perfect for carrying your books.
W: Where are the forms?
