A drunk man walks into a bar. He seats on a stool and asks the bartender for a drink. The bartender politely refuses the man and suggests getting a cab for him. The drunk is surprised. He climbs down of the barstool and staggers out of the bar.

A few minutes later, the same drunk comes into the bar. He seats on a stool and asks the bartender for a drink. The bartender comes over, and politely, but firmly refuses him again and offers to call a cab for him. The drunk looks at the bartender for a moment and angrily walks out of the bar.

A few minutes later, the same drunk bursts into the bar. He seats on a barstool and orders a drink. The bartender comes and reminds the man that he will not serve him any drink, and will call a cab or the police.

The drunk looks at the bartender and hopelessly cries out,

“How many bars do you work at?”
