a question for everyone

i had just clocked back in from lunch when all the comotion happened. a customer had purchased a washer and dryer in appliances and while they where waiting on the associates to bring them up they pulled up to the loading zone outside the exit. they started backing up and i guess they weren't paying attention because they very nearly backed right into the sliding doors but thankfully my head cashier saw them, shouted at them to stop and had them pull forward some but this got me thinking if anyone has worked at a store where someone did hit the doors? or drove their car somewhere they absolutely should not have? we had a lady back into one of the garden center racks when she pulled up to be loaded but never someone hitting or breaking a door with their car.
