Re: Bet they all use smartphones though...
I had a Hell Desk trying to get me to send an engineer to a customer because they had a fault light on a piece of kit. I pointed out that this meant the fault was at the distant site, so suggested he tried checking with them first.
"I've been doing this job 6 months and it is this end..." "I'll see your 6 months, raise you another 4.5 years and a copy of the circuit diagram". The Hell Desk went over my head to file a complaint and an engineer was dispatched.
The engineer snipped the lead to the LED and told them to get someone to investigate the distant end.
Strange, they never phoned back to thank me for my expert fault diagnosis!
