The Barber

One day a priest walks into a barber & asks for a haircut. When the barber finished the priest asked: how much do I owe you? The barber replied: oh don't worry it's free. The next day the barber opens the shop door & finds 3 bottles of whisky from the priest as thanks.
 
On the second day a monk walks into a barber & asks for a haircut. When the barber finished the Monk asked: how much do I owe you? The barber replied: oh don't worry it's free. The next day the barber opens the shop door & finds 3 bottles of brandy as thanks.
 
On the third day a Rabbi walks into a barber & asks for a haircut. When the barber finished the Rabbi asked the same question and the barber again declined payment. The next day the barber opens the shop & finds 3 rabbis standing outside for free haircuts.
