On a positive note, I worked for the Santa Clara, CA Micro Center from 2002 thru 2005, and had a very positive experience there. I started in peripheral sales, and moved to system sales. I worked with the tech guys a lot, and since I'm a computer geek myself, I helped many of my customers troubleshoot issues. I gotta say, if you have a micro center near you, the employees there (in my experience) tend to be much better trained/more knowledgable than the competition, pricing tends to be the same or better than Fry's (comparing the same brand products, not the ultra cheap garbage Fry's often sells), etc etc. I haven't worked there in 4 years, but if it weren't for the fact that the closest store to me is in Tustin, CA (about an hour and a half drive), I'd go there. Highly recommend 'em!
As for the Best Buy thing...I truly hope that idiot was the exception rather than the rule. But, as some of the previous posts have shown, all too often stores like Best Buy are very willing to ignore the crucial role that knowledgable, competent sales/support staff can play in keeping up their reputation. I used to know Micro Center's extended plans inside and out, and that they were far superior to the competition, and it was easy for me to sell people on them because 1) I believed in it and bought them myself on items, and 2) the 3rd party vendor we worked with nearly always followed through on their end, and when they didn't, most of the time the store would try and find a way to make the customer happy. Stores like Best Buy don't tend to do that. And it's too bad, in the long run I think they'd do themselves a lot more good than financial harm.
