Free Hair Cuts

A priest went into a Washington D.C. barbershop and got his hair cut. He then asked how much he owed the barber. “No charge, Father,” the barber said. “I consider it a service to the Lord.” When the barber arrived at his shop the next morning, he found a dozen small prayer books on the stoop along with a thank you note from the priest.
A few days later, a police officer came in. “How much do I owe you?” the cop asked after his haircut. “No charge, officer,” the barber answered. “I consider it a service to my community.” The next morning the barber found a dozen doughnuts on the stoop along with a thank you note from the police officer.
A few days after that, a senator walked in for a haircut. “How much do I owe you?” he asked. “No charge,” the barber replied. “I consider it a service to my country.” The next morning when he arrived at the shop, the barber found a dozen senators waiting on the stoop.
