There is a boutique guitar store near me that only hires professional musicians and although these guys can really play, they are not salesmen. Although Guitar Center hires morons and kids, they are there to sell stuff and try to be helpful. I would rather deal with a well-intentioned idiot than a "know it all" pro who is too busy f*&king around with toys to help me try to spend my money. Oh, and headphones should be required for all practice sessions, and employees (for their sanity).
