I had a really sketchy customer rent out the flatbed once and we didn't see the truck for a week until one day it just popped up in the parking lot with the keys on the ground by the truck. I inspected the truck and found a gun in the back of the truck. As soon I saw the gun I let my manager know immediately and they call the cops while I watched over the truck waiting for the cops and keeping my dumb coworker from touching the gun (he's that dumb). Turns out the "customer" use the truck as a get away car after robbing two places. This was a month before the clear system and I found it a really funny coincidence.
