Re: This smells like BS.
I have. Especially after we had a large number of calls from one of the buildings we looked after where a large number of PCs were suddenly crashing and some were not rebooting.
It turned out that two of "our" onsite engineers were doing PAT testing and hadn't thought about all the possible effects of pulling the plugs without shutting the machines down first. After that, we made sure to shut everything down before letting them loose - even after their Manager gave them a rather stern talking-to.
