I've got a scenario:
There is an attractive 22-year-old young woman in a bar
There is a divorced 44-year-old drunk with his hairpiece falling off his head and his shirt from the 1970s opened exposing his unshowered-in-5 days chest hair
He keeps winking at the girl and touching his "sexy" chest
The girl walks up to him and says "okay, I am a prostitute, I will charge you $50 to sleep with me"
The guy says "Sorry, babe, I was just joking around"
That was extremely sleazy and quite insincere. Good enough? I didn't take enough time to think it out, I just blurted out whatever I could think of. Because it kind of happened in real life once with a friend of a friend , I just exaggerated it and added the twist of prostitution at the end.
