I actually had this happen before, when i was about 20, I had a job at this auto parts factory. Being the friendly person I am i talked to just about every body. Eventually became a line supervisor, one day this woman was really screwing up and i had to reprimand her. She said, Im going to report you for sexual harassment and brought up some casual conversation we had like 6 months prior. I said oh, ok, follow me. Took her to the production supervisor, said ok she has a complaint to file, the woman then told her story to the production supervisor and he looked at me asked me my side of the story. I replied, "Well she left out one important part of the story, she seems to have forgotten how the conversation ended, you know the part where she asked me out for drinks and I turned her down and if you need confirmation of this there was 3 other people involved in the conversation want me to go get them?" Needless to say, I didn't hear anything more about the issue and being as she had done the same thing to 5 other guys she was let go that day.
