I was told this story by another mechanic. We just took over a job from another company, the route guy had not made his first visit but did receive a call about a entrapment. When he arrived he went directly to the car first to see what condition the cab was in before he went up stairs. Car was out of floor level way over our 18'' policy. When he got to the machine room and opened the door to his surprise there was a guy inside. Turns out this guy was paying the previous mechanic a few bucks a week and would let him sleep in that machine room, the bum said the car was making one hell of a noise and he turned off the disconnect cause he could not sleep.
