Haha... I would say a curse... I would never, ever let any dealer wash and detail my car. Even when I placed the order on my car, I specifically told my SA not to prep it and to leave it alone. They did remove the white protective film though. I've had my shares of scratches forming from people who don't care about their job.
My trips to get an oil change, I always put a sign on my window that reads "NO WASH" as well
