Hi IT?
My worst call ever from my hell desk days:
Hi IT? The vending machine is out of crisps.
Me: while I think that's a terrible problem why are you ringing IT?
User: Well it's electric isn't it?
To this day my ex colleagues and friends in IT have a running joke of "Hi, IT? Can you change the light bulb / refil the car with diesel / wipe my arse for me?"
