both of these take place at where I work.
1. We had this one Tesla compute card that just would not work, We had it tested and they said it was fine, but every time we got it back it just would not work. spent like 3 months trying to make it work, with my boss breathing down the back of my neck. The day we finally get it work my boss sends out an email that says we are upgrading. I took the card and went down to the basement and cut the card in half with a saw.
2. One time when repairing a system that kept crashing, because of who had this system I would have to stay till it was done. They simply refused to use another system unless absolutely necessary. Having stayed till 2:30am without success, I took the motherboard out and salvaged what I could. Then I broke the board in half over my knee.
