TIT FOR TAT

A very shy young man goes into a bar and sees a beautiful woman sitting alone. After an hour he gathers enough courage to go and ask her, "Er... Excuse me, but would you mind if I sat here beside you?" She responds in a loud voice : " NO, I DON'T WANT TO SPEND THE NIGHT WITH YOU!" Everyone in the bar turns to stare at them. The young man is surprised, shocked and embarrassed and goes back to his table. After a few minutes the woman walks over to him smiles, apologizes, and says, "You see, I'm a graduate student in psychology and I'm studying how people respond to embarrassing situations." The young man responds loudly with, "WHAT DO YOU MEAN FIVE THOUSAND RUPEES. THATS TOO MUCH !"
