The post reminded me of a story I read a few years back.
It was a picture of a RV that had been on a 4 post lift jack at a motorhome repair facility. Only it had slipped, and one post went into the side of the RV and out the roof - somehow.
The RV owner saw the post, and made some comments about it. I don't know what I would do if a RV facility called up and said "We sort of had a problem while repairing your RV".
I know guy who was test driving a Jaguar he had just repaired and given a tune up and test drive, he crashed it. I think the repair shop owner wanted to just do the body work, paint the car, and get it back to the owner in 4 days.
