Barman  

A man walked into a bar and ordered a glass of white wine. He took a sip of the wine then tossed the remainder in the barman's face.
Before the barman could recover from the surprise, the man began weeping. "I'm really sorry. I keep doing that to barmen. I can't tell you how embarrassing it is to have a compulsion like this."

Far from being angry, the barman was sympathetic. Before long, he was suggesting that the man see a psycho-analyst about his problem. "I happen to have the name of a psycho-analyst," the barman said. "My brother and my wife have both been treated by him, and they say he's as good as they come."

The man wrote down the name of the doctor, thanked the barman and left. The barman smiled, knowing he'd done a good deed for a fellow human being.

Six months later, the man was back. "Did you do what I suggested?" the barman asked, serving a glass of white wine.

"I certainly did," the man said. "I've been seeing the psycho-analyst twice a week." He took a sip of the wine then threw the remainder into the barman's face.
The flustered barman wiped his face with a towel. "The doctor doesn't seem to be doing you any good," he spluttered.

"On the contrary," the man said," he's done me a world of good."
"But you just threw the wine in my face again!" the barman exclaimed.
"Yes," the man replied, "but it doesn't embarrass me anymore!"
