That must be one unusual computer store, I have never met anyone (staff member that is) in a computer store who knew anything useful about computers.
He is the owner of the store. He started out as a hobbyist in a little hole-in-the-wall shop, and proved to be knowledgeable enough that people came to him for their computer hardware in great numbers, forcing him to move to a bigger store and hire a couple of employees. He is now (after about two years) in his third location, bigger than the previous two locations combined, and he still puts in 12-15 hour days there himself. I don't believe that he stocks or sells anything that he hasn't personally tried and approved.
Classic American success story.
