One of the great difficulties of working in Information Technology -- at least, in my workplace -- is that you're never not part of the help desk. It doesn't matter if your official job only involves working on one or two specialized applications, people will call you for all kinds of computer-related problems. (Or, for that matter, sometimes just for technology advice in general, e.g. "What sort of tablet should I buy?")
I mean, all I wanted to do was get a fresh cup of coffee, but in order to reach that grail-shaped coffee pot I had to fight through a horde of error messages, defeat a bulk email setup, and consult the Cell Phone Oracle on behalf of a postulant.
Some days it's just not safe to walk down the hallway.
