Surveillance Camera Catches Valet Crashing Client's Car

As a valet, his only tasks are to park customer’s cars and bring them back when they have to leave, remaining only two things for him to focus on: remembering where the cars are parked and not damaging them in the whole process. Seems like he forgot the latter condition, as he left a car at the top of a ramp going down to the parking lot and stepped out with no apparent reason.

We don’t know if he activated the parking brake and it was not functional, but the car started to slowly roll away from him, speeding down the ramp until it crashed into a wall at the end, leaving the valet going back and forth not knowing what to do next.
