Hello how may I help you? I forgot to return a book last week. How much do I owe in late fees? You want to know about late fees. The total depends on how many days the book is overdue. I only failed to return one book. I understand, one book. How many days is it overdue? About 7 days. For 7 days the total fee would be 35 cents. But if you do not return it today, the fee would go up to 40 cents. Can you return the book today? No I can't. Can you just waive the 40 cents additional fee? No I'm sorry I do not have the power to waive a fee. However you can ask the librarian on staff if they can assist you with this. Is that something you can do? Well, as of now, I can't do anything. I'll just pay the fee then. Thank you for your support of the library.
