I mentioned just a few days ago that I got new racing stripes on my rental car after handing my keys to Hilton's valet car parking service.
It's been elevated to the police. After chatting with the general manager, she interviewed both valet drivers who say they didn't hit anything. Since no-one's taking any responsibility for it, I've had to submit a police report for hit-and-run so insurance matters can be sorted out.
Lesson learned. Always park the car yourself.
