A little old Jewish lady sold pretzels on a street corner for 25 cents each. Every day a young man would leave his office building at lunch time, and as he passed the pretzel stand, he would leave her a quarter, but never take a pretzel.

And this went on for more then 3 years. The two of them never spoke. One day, as the young man passed the old lady’s stand and left his quarter as usual, the pretzel lady spoke to him.

“Sir, I appreciate your business. You are a good customer, but I have to tell you that the pretzel price has gone up to 35 cents.”
