This same dude was in charge of me a year or two later. The same day he did that to me he played a prank on someone driving a 100 ton haul truck, He decided to pull a killswitch on the front while they were in the pit and it completely shut the truck down. The killswitch was not electronic but instead a wire the ran through a pin that was held open. As soon as you pull the switch the pin drops shutting off Fuel to the engine. Mother ******! Thanksgiving day, we were just trying to go home after our work was done and he shut down our biggest truck. Honestly though awesome dude and good friend of mine, really fun to work for.
