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

One day as he approached her stand she said to him, "Sir, I have watched you for months, going by my humble pretzel stand and leaving me a quarter even though you do not take a pretzel. Well, I really appreciate this, but I find it hard to tell you...pretzels have increased to 35 cents."
