I worked for an awful ex-boss. He is/was such a juvenile delinquent he would make fun of people for the way they looked. He wrote up one elderly woman, who limps for taking too much time in the bathroom. He tried to mark her wrong but she disputed it and won because she is smarter than him. He had 2 employees who were his friends come into his office and BS for hours at a time on company time. He is a waste case and only a manager due to family connections.
He is married. Rumors were flying because he would spend over an hour at a new girl's cube everyday. I didn't notice but 1 of my coworkers told me about it. I have a 45 minute lunch time. I have to walk past this girls cube to leave the building. I would go to lunch come back and he would still be there. He is not this girl's manager, he has no reason to be there. This went on for months, until...
Last week I took my afternoon break at 2:30 and they both were walking up the street together. When I saw them I said hello and they both looked like they got caught with their hands in the cookie jar. He has not been at her cube since.
I haven't told anyone in my office about this. I would love to go up to him and say, "Hey I know what you were doing." just to watch him squirm.
