A Franciscan goes into a barber shop to get a haircut. When he is about to pay, the barber tells him he doesn’t charge clergy. The Franciscan replies saying that, although poor and humble, he can afford a haircut, but the barber insists, and the Franciscan finally accepts.
The next day there was a basket of fresh bread at the barber’s door, from the Franciscan priest.
Some days later, a Dominican priest goes to the same barber. Again, when is about to pay, the barber tells him it is his custom not to charge clergy. The Dominican debates with the barber, arguing there is no reason for a free haircut, but the barber insists and the friar finally accepts.
The next day, the barber found at his door a collection of theology books published by the Dominican Order.
A few days later, a Jesuit comes to the same barber shop and gets his hair and beard done. When he goes to pay, the barber tells him the same thing he told the Franciscan and the Jesuit. The Jesuit tells him “I’m a teacher, and hence I’m not wealthy, but I can afford my haircuts.” The barber insists, and the Jesuit finally accepts.
The next day, there were 10 Jesuits lined up at his door.
