How may I help you?
I need to check these books out.
Do you have your library card?
Here it is.
It appears that you have late fees.
Really?
Yes, really.
How much do I owe?
You owe $ 24. 50 in late fees.
I don't have that much today.
I'm sorry, but until you pay it, you won't be able to check out any more books.
I'll pay it as soon as possible.
