Last year I walked in on my boss using the restroom... he was sitting down and reading the newspaper! ... it was mortifiying!
I could not stand the guy and I am fairly tolerant. Some background...he was loud, arrogant, cocky, and just plain annoying. oh and he was a pig...married and always making obscene gestures at coworkers, flirting with younger girls, basically all the makings of a boss from hell going on here. Oh and he wore sweater vests. enough said already?
So I walk in on him sitting there and he looks over from his paper and smiles and says "hi" in a very oddly non-shocked manner. I say "omg...pat i am so sorry!" and i cannot find the handle to the door to close it again so the moment truly seems to last forever.
Because of his notorious reputation I have the best time reciting the story to everyone at work whom I'd ever even made eye contact with once. hehe. I was leaving a few weeks later, I had nothing to lose.
