I worked at a mall Radio Shack in ‘98-‘99. A Gateway store opened up at the other end of the mall. This being the times they were, Radio Shack had partnered with Compaq to sell P2 & (I think) P3 desktops, the beginning of its downfall of selling other companies’ stuff and losing out to places like Best Buy.
We used to emphasize that you could buy a computer with us and go home with it today, whereas down the hall, you could buy it but it would come in the mail later. Their store had demos and the big cow-patterned boxes around, but no inventory.
Also around then, I applied for and got a Gateway-branded, Holstein-patterned credit card, which I promptly maxed out to buy my own first modern computer, a P2 build not from Gateway, but from Midwest Micro. I learned Red Hat Linux on it, reading the manual on break at work even before the computer came, and it began my real career.
So lots of adjacency to Gateway, but no real firsthand experience. They were definitely a force.
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.
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.
