Reviewing a phone call request for information from a car dealership: "I would definitely not do business with this company. It is unacceptable to provide the customer with math problems."

...the "customer" (mystery shopper) asked for MPG values on a new car. The salesperson told him the highway mileage for both 4 and 6 cylinder engines, then said it was "minus 5 miles for the city." Customer is subsequently outraged about having to perform such wizard math as "31 - 5 = ????"
