A man walked in through the front door of a bar. He was obviously drunk.

He staggered up to the bar, sat on a stool, let out a belch, and asked the bartender for a drink.

The bartender politely said, “It looks like you’ve already had plenty. I can’t serve you any more, but I can call you a cab.”

The drunk looked surprised, then scoffed, grumbled, climbed off the stool, and staggered out the front door.

A few minutes later, the same drunk stumbled in through the side door and shouted for a drink.

The bartender came over and replied, still polite but firmer, “No. You’re too drunk. I can call you a cab.”

The drunk glared, cursed, and staggered back out the side door, shaking his head.

A few minutes later, the same drunk burst in through the back door, plopped onto a stool, and demanded a drink.

The bartender leaned in and said, “You’re clearly drunk. You’re getting no drinks. I’m calling you a cab—or the police.”

The drunk stared at him in hopeless anguish and cried, “Man! How many bars do you work at?”
