The owner of an old fashioned barbershop states. The barbers vote Republican, the customers vote Democrat. If the barbers are independent contractors assume we could qualify them as business men. The customers chat up the barber, there is banter back and forth on world affairs, etc. yet the customers(as Democrats) fail to convince the barber (republicans) to change their vote. One could assume the barber has heard it all based on the variety of people he has conversed with whereas the customer is not really in a position to have heard it all (customers chatting with other customers). The hair cut is finished, the Democrat pays for the haircut and offers a "tip" for a job well done to the republican barber. I think the democrat got more than a haircut.
