Nasrudin went to a Turkish bath. As he was poorly dressed the
attendants treated him in a casual manner, gave him only a scrap
of soap and an old towel.
   When he left, Nasrudin gave the two men a gold coin each. He
had not complained, and they could not understand it. Could it
be, they wondered, that if he had been better treated he would
have given an even larger tip?
   The following week the Mulla appeared again. This time, of
course, he was looked after like a king. After being massaged,
perfumed and treated with the utmost deference, he left the 
bath, handing each attendant the smallest possible copper coin.
   ‘This’, said Nasrudin, ‘is for last time. The gold coins were
for this time.’
