A man walks into a bar and orders a drink.
The bartender says, “I can’t serve you. You’ve had too much already.”
The man sighs, leaves, walks around the corner, and comes back in through the side door.
He sits down and orders a drink.
The bartender looks up and says, “I told you five minutes ago, I can’t serve you.”
The man leaves again, walks around the block, and enters through the back door.
He sits down and orders another drink.
The bartender slams his hand on the counter.
“I told you, you’re cut off! Get out!”
The man stares at him and says,
“Man… how many bars do you work at?”
