Good observation Bob, When I did tech support many years ago, on site for Typesetting networks, I always came into shops that were freaking out because something like the Typsetting machine itself was dead. That meant their whole operation was down. They worked on a very time sensitive schedule and they usually didn't have an extra $30 grand machine lying around as a backup.
The first thing I did was check the power cord in the wall. I'm sure you know that many times the plug fell out of the wall and the whole service call wasn't needed if they just would have checked the plug. And when they called we would ask them to check it before we came and they all swore they did.
