Since there's quite a few of us that work in the tech-support industry, why not share your stories? Heck, even if you don't work in tech-support, you've all recieved humorous emails with helpdesk related stories in them..... I know..... cause I sent 'em.
Anyways I'll start it off.
This happened before I began work there, but I'll tell it like I was there
I work in a government building and there was a power outage and nothing was working obviously. The lady that answers the helpdesk gets a call from a certain lady reknown for being dim...
"Hello? I can't get into my email."
Helpdesk lady says, "Is your computer turned on?"
"Um... No, it doesn't appear to be."
And then our lady then goes on to explain how a blackout affects computers.
