This guy staggers into a bar and shouts, "A double whisky please, barman, and a drink for everyone here… and while you're at it, have one yourself."

"Well thank you, sir," says the barman and proceeds to pour everyone their drinks.

Moments later the guy shouts, "Another whisky for me, and the same again for everyone else."

The bartender looks a little worried now and says, "Excuse me, sir, but don't you think you should pay me for that last round first?"

The guy slurs, "I can't. I don't have any money." With this the bartender flies into a rage and literally throws the guy out of the bar.

Twenty minutes later the guy staggers back in and shouts out, "A double whisky for me, and a drink for all my friends."

"I suppose you'll be offering me a drink too?" the barman asks, marveling at the guy's nerve.

"Not likely," slurs the guy, "You get nasty when you drink!"
