Learnt from you

An introvert went to bar and spots a pretty looking woman sitting on the
stool. He mustered all his courage for long time, then timidly approached and
asked her, "Ma' am, would be OK if sit here and talk with you?"

She was alert, suspecting this man, and responds by yelling, "No, I won't
sleep with you tonight!"

Customers in the bar started staring at them. The embarrassed guy quickly
returns to his table dejected and ashamed.

The young woman, waits a little and then goes to the guy to apologize. With
a smile on her face she says, "I am sorry if I embarrassed you. You see, I am
a college student in psychiatry and I am putting together a thesis as to how
people react to embarrassing moments."

The cunning guy now yells loudly, "What do you mean by $500?"
