I had another fuck up at work.
We needed to install a 1080 gtx in a new $4K+ workstation. Note that installing hardware isn't my job but obviously I know how to install graphics cards, done it hundreds of time. The main boss was watching me. As I was installing the card though it got stuck. I think it was where the little pcie clip is and the edge of the pcb got stuck in there weird.
I could tell he just thought I was a complete moron. Usually when something like this happens I just gently rock the graphics card free. He thought I was being forceful and said "Just stop don't touch anything" and variations of that while I was taking a look. I know I could have freed it if he would have let me but I did as he said. He asked me to get a mobo schematic and when I came back he had settled the card into the slot.
