Paul is at a Ford dealership, getting a safety inspection and emissions test. He also needs new windshield wipers.
Paul: How much do new windshield wipers cost?
Woman at Ford dealership: Oh, I don't know, $20.
Paul: Oh, that's not unreasonable, add that on.
Paul goes to work.
Later that day...
Paul is at the Ford dealership, picking up his car and paying bill.
Paul: Why are there two $20 charges on this bill?
Same woman at Ford dealership: Oh, that one is for the driver-side wiper, and that one is for the passenger-side wiper.
Paul (thinking in his head): WHY THE HELL DIDN'T YOU TELL ME THAT THE $20 WAS ONLY FOR ONE WIPER?!! WHO ONLY BUYS ONE WIPER??? IT'S NO WONDER PEOPLE DON'T TRUST DEALERSHIPS, YOU FRIGGIN' IDIOT.
Paul: Thank you.
