Several years ago, the valet at the Grand Hyatt Seattle wiped out the driver's side (from the front bumper to the rear bumper) of my Hertz rental.
The valet guy brought my car around and tossed me the keys...guess he didn't notice that the rearview mirror was hanging off of the door.
That was fun fighting with the Hyatt and their valet contractor. I now do a quick "walk around" the car with the valet before they drive away.
