Hello how may I help you? I have a question about my late fees What would you like to know? How much do I owe? What is your library card number? 123 You owe $456 in late fees. okay I'd like to pay that off in cash right now. Sorry but the library does not accept cash, only credit. Well if you want to be paid, I only have cash. Sorry that is the policy. And since you are belligerent we are adding an addition 25 cent fee.
