Hitting on someone is not "viciously sexist." Nor is telling someone you intend to hit on them for half an hour, later. Saying you'd like to see someone in your bed is not viciously sexist, it's just terribly unoriginal, right up there with "Is that a mirror in your pocket? Cuz I can see me in your pants."
If the behavior is unacceptable, don't accept it. It's that simple. If you want money from someone but don't like the cut of their jib, WALK AWAY.
Imagine if you were taking your kids with you to apply for a home loan. You weren't on food stamps or anything - you just wanted a loan. What if the loan officer looked at your kids and said, "What a bunch of ugly little brats. Glad they're not mine."
Would you smile and stuff down your feelings and try to take his money anyway? Commit yourself to a working relationship with that guy and earn him a commission?
Or would you grab your kids' hands and walk out?
If you don't protect yourself, nobody else will. If you don't respect yourself, nobody else will.
But seriously, telling somebody you plan to hit on them is tactless and rude, but it is not sexist. It's just dumb.
If you want the money more than you want respect, well, you're not going to get respect.
Wow. So it's HER fault that she doesn't get respect because she doesn't handle viciously sexist comments properly?
