In the film "Ferris Buller's Day Off" a trio of kids playing hooky take off in a 1961 Ferrari GT California, owned by the father of the nervous and twitchy member of the group, Cameron. When they pull into a public garage Cameron has a list of reason why they shouldn't leave the car with the self described professional valets.
"It could get wrecked, stolen, scratched, breathed on wrong..."
While your car may not be a rare classic, that doesn't mean you shouldn't be concerned about its safety, even in the hands of even "professionals".
This valet's panicked realization and futile attempt at chasing down the runaway SUV shows he didn't have bad intentions, just poor concentration. A pull at the hand brake, or leaving the car in gear was all that was needed to save this vehicle's front end and his job.
