Here's a new one. I returned a car to Hertz DCA this afternoon, a car I'd picked up in BWI. The agent looked inside and told me if I didn't clean out the car I was going to be charged a cleaning fee. I'd only had the car a day and a half so it wasn't dirty. I said that was absurd and she insisted. I threw out three McDonalds cups, a receipt and a straw wrapper to make her happy.
