Before I worked at TSS doing in-home PC repair, I did a short stint at Radio Shack and got the Compaq experience you described. I remember going to the introduction event for the Compaq roll-out into Radio Shack stores, I was sitting in a large hotel ballroom with like 100 other Radio Shack sales folks. The Compaq guy was asking questions from the audience and I was literally the only person there who could answer questions like "what motherboard interface did the Pentium 2 use" (it was the first cpu to use a slot (Slot 1) versus a socket which was a big deal back then). I had dropped into the event straight after class at ITT, so I was just wearing casual attire and didn't think anything of it. Apparently that was a mistake, one of the higher up sales guys got offended and complained to my manager. I was offended that apparently no one else there knew anything technical at all, lol. Thankfully I left that job not long after.

I was spending all my time learning computers, and I was starting to build systems for family and friends. Once I was lent out to another Radio Shack store that was short handed and the other salesmen kinda lamented not being able to afford the Compaq a customer was buying. Afterwords, I tried to explain to him that I could easily build him a nicer system for a fraction of what we sold Compaq's for. He was still not interested, I think he was way more broke than I realized. I grew up broke too, but I also had my eyes set on improving my situation. Was kind of a wake-up-moment that most people around me had minimal ambition about this.

I also remember having to push cell phones at RS then too, I think we pushed a lot of Sprint phones. I was still fairly young and was just learning about phreaking, but I remember my boss telling people Sprint phones couldn't be cloned like analog cell phones could back then (I disagreed, but I had to agree it was harder at least). It was apparently a thing that your analog cell phone could be cloned over the air and suddenly your bill would be crazy that month. I only ever heard rumors about that kind of thing happening.

I worked at Best Buy and when the Gateway country store opened up they came in and offered most of our sales floor employees big raises and benefits.

Sadly I don't think the store stayed open much more than a year.
