A Rabbi who was late for a golf game was rather curt with several people whose phone calls kept delaying him.
The next day his secretary said "Rabbi, several members of the congregation were really upset with you when you cut them short yesterday."
At that point, a man who had been sitting within earshot in the reception room got up and departed hurriedly.
"Who was that?" asked the Rabbi.
"Oh, that was Mr. Ruthenberg." she answered. "He wanted to speak to you about a circumcision for his son."
