Beers For Everyone

A guy walked into a bar and said "Beers for everyone, even you, Bartender." But when it was time to pay, the guy didn't have the money, so the bartender beat him up. The next day the guy did the same thing, ordered a beer for everyone, even the bartender, and the bartender beat him up since the guy couldn't pay. Then the next day, the guy said "Beers for everyone! But not you, bartender!" The bartender said "Why?" The guy replied "You're violent when you're drunk!"
