This happened to a used car dealer friend of mine, it was in the local newspaper.
Preface:
This used car dealer friend drops off about 20 cars per week to get detailed at the local detail shop. This car dealer is a real AH, no one I know likes him. I have to agree, he is annoying. He always beats the detailer up for price, tells him he does a crap job on every car and was paying him only $60 per car. (His rotten personality in effect)
Action:
The car rotten dealer goes to pick up a car one night and notices a scuff in the car door that he wanted removed. He told the detail guy to bend over and look closer; the scuff was there and very noticeable. When the detailer bent over to look at the scuff, the car dealer yanked the door open hard, hitting the detail guy in the face. The rotten car dealer said, "your work sucks, I’m not coming back". The detail guy left bleeding on the street.
Here is where it gets good:
The detailer calls the police and gets the rotten car dealer arrested for assault. The detailer then proceeds to physically damage the 15 or so cars the rotten car dealer had at his shop. The car dealer goes to court and gets no punishment because he said he slipped on tire dressing on the ground and the door hit the detailer by accident, he in turn sues the detail shop owner for the damages to the 15+ cars and wins big. The detail shop closed because the owners insurance would not cover self inflicted vandalism and had to attempt to pay out of his thin pocket.
Moral of the story:
The customer is always right, be careful who you choose as customers....
