When I returned a recipe book to my local library, the librarian noticed there was water damage to the book and asked me to pay for it. I agreed, but as I wasn’t carrying any money, I said I would pay next time I was in.
There was a different librarian on duty the next day when I dropped by with the money. She swiped my library card and my account came up on the computer screen.
In the “notes” section, it read: “Customer says he’ll hand in the $20 next time, but I don’t think he will.”
