I used to own & operate a computer repair shop and this thread will have stories from it. Most prominently there will be stories about a couple characters who worked for another business with which I shared the building. I call them Redneck Rick Moranis (RRM for short) and Scruffy. There's also Car Boss, Valve Boss, Queen Natitsya (Valve Boss's Ukrainian mail-order wife), Buttgirl, and some regular customers like Interrobang and Cheeto Pockets.
Coming soon, when I get time to dig through my archived posts on SA so I don't have to try to remember and write them again.
