Years ago, I had a friend who worked at Best Buy and was fired (he's a nice guy, but lazy, so I'm not surprised). He then went to work to work at Circuit City. He found out that most everyone who worked there was also fired from Best Buy.
Funnily enough, in my town there used to be a Future Shop, and then a Best Buy sprung up in the new commercial district, but apparently couldn't compete because it closed 2 years later. Then about a year later Best Buy bought Future Shop and they re-branded the existing Future Shop to Best Buy.
