Who earns a living driving their customers away?

One day, my sister was driving her brand new car home from the grocery store. Driving defensively, her senses were sharpened and she followed all the traffic rules: staying within the speed limit, signaling before turns or lane changes, keeping a watch for pedestrians, turning carefully. When she heard a strange sound from the rear end of the car, she was puzzled. At first she thought she had hit a curb or something. But the sound reoccurred every time she turned a corner. Instead of going home, she drove directly to the dealer where she bought the car. She explained the noise and a mechanic did a thorough inspection. “I see nothing wrong,” he said. My sister persisted, “but every time I go around a corner, it goes, ka-lunk, ka-lunk. Something is wrong.” So the mechanic took it for a test drive. When he returned, barely able to keep the smile from his face, he said, “Ma’am, I believe the sound is coming from the watermelon in your trunk.”
