Usually it is a 2:00 a.m. and I have to drive an hour to go get some part or piece of equipment and then get back and get it fixed before the morning rush
I got that call last night. I had just settled down for slumber about 12:20am; then the phone rings at 12:45am. central computer down. Luckily, there was another guy available as I would have had to call my in-laws to watch the kids.
