The incompetent IT guys: At my college we ran a number of PC labs and a number of Mac labs. The guys in IT clearly had training enough to _use_ macs, but they really didn't understand the concepts of network administration. We were a design program and one of the requirements was that we be able to install custom fonts for use in projects. One day people got to class the morning a massive project was due and nobody could open their project files to print them! I discovered that the _user_ font folder had simply been replaced with a shortcut to the _system_ font folder, and we didn't have the permission to restore it. So they had deleted every users custom fonts already, and now after I discovered and proved their error they had to restore it to the way it was. They looked like _heros_ for fixing the big problem on the worst day, but ultimately it was only their incompetence that created the problem in the first place. Their reasoning was that TTF fonts can sometimes carry viruses within them that infect Windows computers… (And we use OTF fonts on OS X)
