A man walks into the front door of a bar.
He is obviously drunk, and staggers up to the bar, seats himself on a stool, and with a belch,
Asks the bartender for a drink.
The bartender politely informs the man that it appears he has already had plenty to drink,
He could not be served additional liquor at this bar, and could a cab be called for him?
The drunk is briefly surprised, then softly scoffs, grumbles,
Climbs down off of the stool and staggers out the front door.
A few minutes later, the same drunk stumbles in the side door of the same bar.
He wobbles up to the bar and hollers for a drink.
The bartender comes over and, still politely-but more firmly,
Refuses to serve the man due to his inebriation, and again offers to call a cab.
The drunk looks at the bartender for a moment angrily, curses, and shows himself out the side door,
All the while grumbling and shaking his head.
A few minutes later, the same drunk bursts in through the back door of the bar.
He plops himself down on a bar stool, gathers his wits and belligerently orders a drink.
The bartender comes over and emphatically reminds the man that he is clearly drunk,
Will not be served a drink, and either a cab or the police will be called immediately.
The surprised drunk looks at the bartender, and in hopeless anguish, cries,
How many bars do you work at.
