No, it was. There was a power cut to the entire building, but the person calling thought that somehow their computer should continue working even though nothing else had power. And they only mentioned it to the support guy after 45 minutes of trying different things to make the machine boot up.
I don't see why the support guy should be fired for this. There should be limits to the depths of stupidity they should have to deal with. Computers are complicated instruments, and if someone is that idiotic, maybe they shouldn't be using a computer. You can't expect everyone to be completely unflappable no matter how frustrating their job is.
