I used to work as a fire alarm and security system engineer, and my boss was a dodgy maverick, picking up contracts here and there. He somehow had me responsible for a shopping centre that was about 150 miles away ,and it housed the cctv for the entire town centre (cctv is big in the UK). I was on a salary, so didn't get overtime. One Saturday morning I got a call saying all the cctv system was down, and that I needed to got sort it out ASAP! Drove for 4 hours, and got to the control room, where I was confronted with a totally dead system - all the monitors were on, but all black screens. I asked the guy what happened, mostly to stall for a bit as I'd never been on site before and there were no schematics available, and I was expecting to be there for days. He told me that he'd gone to put the kettle on, come back and when he came back, it was all dead. I asked where the kettle was, and he looked bemused,but showed me. Instead of it being in a rest room, it was located on a shelf behind the equipment rack. I took a closer look, and saw that it was plugged into the power strip that was built into the rack, and the cable was twisted round other power cables, one of which was... The demultiplexer that carried all the cctv camera signals from round the town, and which had been pulled out (iec mains lead, easily done). Pushed it back in by 5mm, went round the front to see all the monitors on... Said "thanks for that" to the guy, got the paperwork signed and left. Spent a total of 15 minutes on site, and over 8 driving as the traffic was terrible on the way home.
