Did a story on /R/talesfromtechsupport back in the day.

I worked as the IT guy for an advertisement company and there was one sales monkey who for the life of her could not walk 5 steps from the printer to fill the paper back up, she would hound me until I did. Well after a few months of trying to show her red light here means more paper is needed she would start complaining to her boss about how the printer is always broken.
Well one day I snapped at her and yelled at her to use her fucking brain.
She filed a hr complaint about me citing the phone call and general inability to keep the printers working.
When the meeting with HR my manager and I was scheduled I insisted on having the sales manager there too.
Both of them went to bat for me against the complaint and at the end of the meeting the complaint was dismissed without merit.

The reason she was to insistent on the printer working was she would print out any email she got, write down the reply on the paper, type up the reply, print her reply, then delete the original email.
Once that was discovered she didn't last much longer.
