A guy goes into a very busy bar and says to the bartender, "Give me a beer, give everyone in the place a beer and have one yourself."

The bartender serves everyone a beer and draws one for himself. He walks over to the benefactor, toasts him and asks for his money.

The man tells him that ran out of money a long while back. The bartender physically ejects him from the bar and throws him out on the sidewalk.

The man picks himself up and walks back into bar. He crawls on a stool and says to the bartender, "Give me a beer and give everyone here a beer, but none for you.  You get too mean when you drink".
