I wasn't going to chime in here, since I'm likely to just get bombarded, but we're not all flunkees. I have a BA and am going back this fall to grab a BS in Physics, too. Yes, because I don't want to be stuck at GC forever, but it's not all bad given the right management. We are paid on commission, and it can actually be a pretty good job if you actually help customers (and thus make sales), but it can also be a pain in the butt when we get people coming in with your attitude and think we're all idiots. Some of us might be, but coming in with that attitude isn't likely to get you any help. I can't tell you how many times someone won't listen to me because I can't possibly know what I'm talking about and buys what they think they need, only to bring it back the next day because it doesn't work like they thought it would. But I don't give them an attitude, I just tell them again what I think they need. Sometimes, they listen, sometimes they don't. There are also a lot of people coming in and plugging stuff in and moving stuff around without asking and frequently blowing tubes or transformers in expensive amps that we can't really sell anymore, so please understand when we don't always trust customers to plug up correctly.
And to also counter your point that no one who knows anything would work at GC - they actually provide great health insurance, an opportunity to make a lot of money (our top salesman makes more than $200k a year), and a fairly laid-back work environment. At the location where I work, two of our pro audio salesmen operate moderately successful recording studios, two run live sound in the area, and one is quite literally a rocket scientist. A lot of the people I work with could easily do something else for a living, but they like helping other people, so they work at GC. So please keep an open mind.
