She Completely Humiliates Him In A Bar. But What Happens Next? Didn't See That Coming

At a bar, Archie approaches Zoe, a pretty girl drinking by herself. 

He tries to make conversation, offers to buy her a drink, when suddenly she yells, "No, I won't sleep with you tonight, you pig!" 

Everyone in the bar stops and stares. Completely embarrassed, Archie slinks back to his table with a red face. 

After a few minutes, Zoe walks over to him and apologizes. She smiles and says, "I'm sorry if I embarrassed you. I'm a graduate student in psychology, and I'm studying how people respond to embarrassing public situations."

To which Archie responds, as loudly as possible, "What do you mean $200 for a BJ?!"
