A: May I help you?

B: Yes. Last month I borrow a book from library. But I can not find it any more.

A: I am sorry to hear that.

B: What should I do?

A: Oh, that book is intended to return ten days later. So, you may have ten days to find it. If you could not find it at last, you may buy a new one to return it for instead. Or, you may pay the fines according to the fines policy.

B: How much are the fines?

A: It is intended to be twice of the book’s price.

B: Thank you. I will look for it again. If I could not find it, I will buy a new one.
