Used to work in robotics. The QA folk were obviously very much sticklers for the full process of enabling the hardware interlocks before getting near the moving bits. One time a manager got mad at them for taking so long going through the full interlock process while repeating a failure mode. He therefore went up to the machine saying "look, it failed so it's stopped, that's how the code works!" At that point our beta version of our CI requisitioned that bot (as the interlock wasn't the only process corner that the manager was trying to cut the bot wasn't marked as reserved in the CI system), it started initializing and broke his arm.

I'm just glad that ultimately he was the only one who faced physical consequences for his poor choices. And thankful that the consequences weren't that bad at the end of the day; a broken arm is way better than a cracked open skull.
