Back in the 90s I was working as an engineer in Virginia (at a non-bike related company). Some customer was on site to receive a demo of the system he was considering purchasing, and something or the other wasn't working right. I was called on scene to help diagnose the issue, and it became apparent that we'd need to start disassembling and replacing some parts.

The only tools needed to open these things were nut drivers and screwdrivers, so I grabbed one from Tom's desk which was three steps away from where we were standing. Tom returned from wherever he was (coffee break or something) and immediately deduced that somebody had borrowed his tools, which started the scariest rant I've ever been witness to.

I mentioned that I had his tools right here, just need to diagnose this system, etc., but Tom was in full-on scream and curse mode. To me, that would have been ok... Except that we had the VP of sales, VP of engineering, and the customer standing right there as well. Not so ok. Tom got fired basically on the spot. One of the most uncomfortable situations I've ever been in.
