A strange string of events occurred in San Francisco's Tenderloin neighborhood Monday morning.
A valet attendant left a red Mustang running while it was in reverse in a parking garage on Jones Street near O' Farrell Street.
The car went down a ramp inside a garage, hit a sprinkler system and flooded part of the floor.
At the same time, a Mercedes hit a fire truck parked outside.
Police say no one was injured in either incident.
