Hello how may I help you? I have some library fees I need to pay. Alright. What amount would you like to pay? $5, in cash. Unfortunately, the library cannot accept cash for late fees. What? That's outrageous. I refuse to accept that. The amount to be paid is now $5.25. No. I refuse. I'm going to drive by your building and fling the coins out of my car window. You'll HAVE to take it. Thank you for your donation! The fee to be paid by card is now $5.50. I won't pay except by cash! The fee to be paid by card is now $5.75.
