The train was travelling along when a beautiful young woman entered the compartment which was deserted except for a businessman reading his paper. The man peered over his paper and asked "Would you let me kiss you for fifty pence?"
"Certainly not!" exclaimed the young woman, and the businessman returned to his paper.
A short while later he looked across again and said "Would you let me kiss you for a thousand pounds?"
After a brief pause, the woman replied "yes, I suppose I would." Again the man returned to his newspaper.
A few minutes later the man asked "Would you let me kiss you for five pounds?"
"Certainly not!" replied the young woman, getting angry now "What kind of girl do you take me for?"
"We've already established that" replied the man, "We're just haggling over the price!"
