Hello how may I help you? How much do I owe in late fees? You currently owe $100 in late fees. That's a lot. How long was my last book overdue Your last book was overdue by one day. Would you like to pay that now? Yes. But I would like to pay in cash. Sorry, we only take credit. But I only have cash at the moment. It is our policy not to take cash. That's not a good policy. I will have to increase your fee by 25 cents for getting belligerent. Enjoy then.
