One day, a florist visited a barber for a haircut. When he asked for the bill, the barber replied, "I cannot accept money from you. I'm doing community service this week." Pleased, the florist left. The next morning, the barber found a 'Thank you' card and a dozen roses at his door.
Later, a police officer came for a haircut. When he tried to pay, the barber gave the same reply. The officer left happily. The following morning, a 'Thank you' card and a dozen donuts awaited the barber.
That same day, a college professor came in. Upon hearing the barber's offer of free service, he was delighted and left. The next day, the barber discovered a 'Thank you' card and a dozen books, including titles like "How to Improve Your Business."
Finally, a Congressman arrived for a haircut and received the same complimentary service. He was very happy as he departed.
The next morning, when the barber went to open his shop, there... waiting at his door...
...were a dozen Congressmen lined up for a free haircut.
