Barber...
An airman finds a barber shop near the base and goes inside for a haircut. After getting a nice, short flat-top, the airman asks how much he should pay.
"No charge, son" replies the barber, "Your dedication and sacrifice in the service of our nation is payment enough."
The next day, as he opens shop, the barber finds a squadron T-shirt and a thank-you note left by his customer. Later that day, a staff sergeant comes in, asking the barber to take a little bit off the sides. When the haircut was complete and the NCO reaches for his wallet, the barber again says:
"No charge, sergeant. Your dedication and sacrifice in the service of our nation is payment enough."
The next day, as he opens shop, he is pleased to find an Air Force hat and a squadron coin by the door, with a thank-you note. Later that day, a colonel comes in, asking if the barber can do something to cover his bald spot. The barber obliges, and when it comes time to pay, he again says:
"No charge, sir. Your dedication and sacrifice in the service of our nation is payment enough."
The barber comes to work the next day and finds on his doorstep ... three more Air Force colonels.
