A priest goes this barber, gets a haircut, thanks the barber, and asks how much he owes him.
The barber says, "Father, you're a noble man, a man of honor, I couldn't charge you, it's on the house."
The priest says, "Thank you very much" and leaves. The next day, on the doorstep of the barbershop are 12 gold coins.
A few days later, a Buddhist monk goes in for a shave and a shine, and when the time comes to pay the barber says, "No money, please, you're a spiritual leader, a man of the people, it's on the house."
The next day, magically he finds 12 coins on the doorstep.
The following week a “Holy man” comes in, gets a head shave, goes to pay and the barber says, "you’re a “holy” person, I can't take any money from you, It’s on the house. Go in peace.
The next day, on the doorstep of the barbershop there is a queue of 12 “Holy men”.
