While shopping in the produce department of the local grocery store, a demanding customer asked to have a watermelon cut in half.

I told the lady that we don't normally do this. After being pushed for about five minutes, I took the melon to the backroom and said to my co-worker John, "I need this cut in half so this mean lady can buy it."

I did not know that she had followed me to the backroom. I turned around and quickly said, "And this lady would like the other half!"
