An old man operated a street corner pretzel stand, selling the pretzels for a quarter each.

Each day at lunch time, a young lawyer would pass the stand, leave the man twenty-five cents, but never take a pretzel.

This continued for a number of years and throughout¹ that time, they had never spoken.

One day as the lawyer passed the pretzel stand, he left his quarter as usual and the old man finally spoke² to him.

"Sir, I do appreciate³ your business and you've been an excellent customer, but I must tell you that the price for the pretzels has increased to thirty-five cents."
