Too drunk

An obnoxious drunk stumbles into the front door of a bar and orders a drink, the bartender says,
“No way, buddy, you’re too drunk.”
A few minutes later, the drunk comes in though the bathroom. Again he slurs, “Give me a drink,” and the bartender says, “No, man, I told you last time — you’re too drunk”
Five minutes later the guy comes in though the back door and orders a drink, again the bartender says, “You’re too drunk”
The drunk scratches his head and says “Dang, I must be. The last two places said the same thing.”
