I have been reading these posts and getting a good laugh, but also have some memories coming back to me.
When I was a kid, I was obsessed with working at RadioShack when I was old enough. I spent countless hours in the local stores where I grew up, looking at all of the "toys" and yes, I pestered the people working there just to get a chance to turn on the scanners, amateur gear and so on.
Fast forward to 1999 and I got my wish. My manager was a ham and as soon as he met me, he started to ask about my background. When I mentioned I was amateur licensed, we started to talk more tech and he said I was perfect for the job. One thing I learned was, if you were going to be a RadioShack manager and you cared about your employees, you were never going to make it. Our DM made his life hell because he always put us first, above the stupid policies they would hand down over the most petty things. He quit and then there was a string of high school drop out managers (including an ex-con). Things just got worse.
The part I got sick of was, most of the people I worked with were exactly what others have described "You've got questions, We've got stupid looks". The other people I worked with were twice my age, minimal education and dumber than a box of rocks. They were the first to grab every customer that came in the store, if the person was looking for parts, they sent them to me so they wouldn't get tied up with that while they could peddle a cell phone, sat system, ect. This sucked for me since I was already part time and making a lower commission rate than they were. However, those same people knew when they came into the store who to talk to for real answers.
The upside to this was, they were usually hams, scanner guys or some other RF related hobbiest and they bought a lot of CB/Ham/Scanner gear from me. Not to mention, I would program scanners for them and they always took care of me under the table (not allowed by RS policy, but I think the statute of limitations is up on that now

).
Sometimes the customer would work with one of the other salesman for a while, then I would get called over to answer a technical question like how to hook something up. This usually helped seal the deal, since the customer now had a better feeling about what they were buying and felt like they wern't in the dark about how it worked, ect. Of course, once they decided to buy, the same dumb-*** salesman would walk over and take complete credit for the sale. Usually some high dollar items like a TV, DVD and surround system. Easily adding up to over $1000.
I quit when I was offered a job with Motorola. Never looked back. Now days, if I go into an RS for anything, I go in with the specific thing in mind and where to find it. If I can't find it myself, I leave and find it online, elsewhere...usually cheaper.
