There's a couple guys at the local Best Buy where I live that are pretty good. I will test some by acting a noob just to see what they say. It's always nice when you go into a place like that and nicely tell them stuff and actually teach them. I once asked if they carried Wireless 802.11n directional antennas and the dude I asked said they did not. So I walked to the shelf behind him and 3 feet away on the bottom of the shelf picked one up and showed it to him. I then smiled, and walked away. Gotta test those folks! At least I like to. It is really cool though when you do hold conversation with someone who actually does know their a55 from their elbow and ya wind up making a "store friend" that way. They'll remember you because you aren't a noob like 98% of the people they deal with.
