a customer wanted a book that we didn't have in stock, so i offered to order it for her. she wanted it shipped to her house, so i set up the order, printed out the form, and told her that she could pay for it at any register.
she had her money out already, and asked "i can't pay for it here?"
i said "no, you can pay for it at any register-" and started to say "this is just information" but she cut me off.
"OH! this is just community service?"
i smiled and said "yes, i'm serving my time."
