Hello how may I help you? I would like to pay my library late fees. Sure, we accept Visa and Mastercard. I want to pay them in cash. I'm sorry, but we do not accept payment in cash. If you want me to pay your late fees, you will accept my cash. We do not accept late fees in cash. We do not keep cash at the library. It attracts robbers. Well, it looks like I won't be paying my late fees. I am adding 25 cents to your late for for being rude. Uh oh, the robbers will have more incentive with the extra 25 cents in the library. Won't matter since you won't take my money. That's another 25 cents.
