Years ago one of the car dealers had a parts manager who would sell parts out the back door and pocket the proceeds. Working at that dealership proved very lucrative for him... until he was fired for selling parts out the back door and pocketing the proceeds.
Funny how years later, where I work now, one of the mid-level supervisors was taking company supplies for use in his own business. Someone squealed on him and he was forced to flee the state before he could be tried and jailed. Ironically he was next in line to become department head.
I would, of course, never suggest doing sucha thing.
I'm just a spectator and the world is my theater.
