A: Can I help you?

B: Yeah. I just want to know how do I borrow a book.

A: When you have found the books you want, take them to the service desk. And the librarian will deal with it.

B: Should I show them my library card?

A: Oh, yes. Be sure your library card is with you. Without it, you can not borrow any books.

B: How many books can I borrow at one time?

A: You can borrow 5 books at one time.

B: How about returning the books?

A: Oh, it is so easy. Just take them to the service desk too. And bring your library card with you.

B: Thank you very much!

A: It’s my pleasure!
