A man walked in the front door of a bar. He was obviously drunk, and staggered up to the bar. He took a seat and belched out a request for a drink.
The bartender politely informed the man that it appeared he had already had one too many and could not be served. The bartender then offered to call a cab for the inebriated fellow.
The drunk was somewhat dismayed, then with a grumble he climbed off the bar stool and staggered out the front door.
A few minutes later, the same drunk stumbled in the side door of the bar. He hobbled up to the bar and hollered for a drink.
The bartender came over and politely refused service to the man due to his level of intoxication, and again offered to call a cab.
The drunk looked at the bartender angrily, cursed, and shows himself out the side door.
A few minutes later, the same drunk found his way in through the back door of the bar. He plopped himself up on a bar stool, and belligerently ordered a drink.
The bartender came over and emphatically reminded the man that he is clearly drunk and will not be served any alcohol, and that either a cab or the police would be called immediately.
The surprised drunk looked at the bartender, and in hopeless anguish, cried “Just how many bars do you work at?”
