I was working at a USAF base and the CPU module wouldn't plug into a machine even though the test report said it had been working at the factory. I was in the data center late at night when the Lt Col asked what I was doing and I mentioned that I needed to cut the metal bracket just a bit but I needed to protect the board from the metal shavings and that had to be in an anti-static environment. He suggested I take it home after learning I did have the proper tools. I told him there is no way I was going to take that out of the machine room without the proper paperwork based on cost per ounce, it was more expensive that nearly everything else on the base there were were some very expensive things on that base.
