My son is an IT guy, and I sometimes email him at his job to ask how to fix something at my job. Any my husband is not tech savvy at all, so when he asks something.....boy, watch out!
We had an IT guy with a sense of humor.
Told one person that he determined their problem was between the keyboard and chair.
One other case, he said it was a "one D ten T error"
