So much depends on what profession you are in. As a lawyer, I've had some inappropriate things said, but it is rare. I think men are intimidated to say anything to a woman in a suit who has that no-nonsense look on her face, but it happens some. When I was still in school, that shit happened all the time. For the most part, as long as they held no power over me and didn't touch me or demand anything, I laughed at them.
When I was in college, I had a lab professor tell me "your grade is entirely dependant on how nice you're willing to be to me." My reply was, "I hope you like how nice I've been so far, because it isn't getting any better. Try that shit on a stupid girl. I already have an A."
