If you were in this situation, would you just keep working on the car? This mechanic was working on a customer’s car when the police showed up. “Eh, it’s probably for the neighbors,” he likely thought.

Nope. While he was hard at work on the customer’s car, the customer himself was apparently being arrested on drug charges. The professional the mechanic is, he just put his head down and went back to work. That’s the guy you want fixing your car!
