So whats the worst that can happen when you take a flat tire into a shop to be repaired? Would you believe a demolished front door and a trip to the hospital?
Take a look at what happened to my car:


Apparently, the technician was in a hurry to back the car up, and did so with the front door open which he was sort of holding closed with his hand. He commenced to back up and clip the side of the garage. This then pulled the door back to its new *improved* position. The best part is, it also pulled him out of the car since he was still holding it. In what I can only assume is the shock of the moment, he depressed the gas pedal instead of the brakes resulting in more damage, complete ejection from the car, a knock-out, and a ride in an ambulance.
Congradulations! Now we know why doors should be closed before driving.
