Sounds like one of those egomaniacs that somehow passed medical school and thinks that gives them the right to treat everyone else like ****. I've known a few of them, they need to have a real life situation that teaches them they are no better than anyone else. Hang in there in 3 months you'll be rid of the jerk. Actually you might try teaching him math, a pharmacy that's minutes away versus one that's hours away? One that's worked for you for years versus one that screwed up? That's a no brainier. Maybe they used him for a dummy in med school and removed his brain?
