That is reminiscent of a particularly sleazy Honda dealership at which I stopped years ago, while car shopping. I allowed them to take my old car into the shop in order to assess its trade-in value. When I was ready to leave (without buying one of their cars), they claimed that they couldn’t find my car keys.
I stood in the middle of the showroom floor with my cellphone, and announced that they had 5 minutes to locate my keys, or I would phone the cops.
It’s amazing how they were suddenly able to locate my car keys, in the space of about 2 minutes. Needless to say, I would never return to that dealership.
