It wasn't me doing the telling off, but I once had a manager who was a massive dick. Supposedly he was a former CEO and millionaire and he looked down on all of us for being manual laborers. Every week he would call a shop-wide meeting where he would yell at us, call us fuckers, and brag about how he didn't have to work as hard as us because of his education and work experience. He also liked to make us work mandatory weekends, and one Saturday after the shift ended his laptop went missing. Apparently it had a lot of important data on it, and for weeks he was begging for it back, he even offered a cash reward if it was brought back to him. Eventually someone found it stashed in a cooler with the screen ripped off. I think he got the message because after his laptop was found like that he started being a lot nicer to us.
