May I help you?
I would like to check out these books.
May I see your library card, please?
Yes. Here you go.
Apparently, you have unpaid late fees.
I do?
You owe some money.
Exactly how much do I owe?
You owe $ 24. 50.
I won't be able to pay that right now.
Until you pay it, you can't check out books.
I will pay it. Don't worry.
