Cheap Beer

A man in a pub asks for a beer.
The barman says, “Sure, that’ll be one dollar.”
“One dollar?” exclaims the man.
Reading the menu, he says, “Could I have steak and chips?”
“Certainly,” says the barman, “that’ll be two dollars.”
“Two dollars?” cries the man. “You’re joking. Where’s the guy who owns this place?”
The barman says, “Upstairs, with my wife.”
The man says, “What’s he doing upstairs with your wife?”
The barman says, “The same thing I’m doing to his business.”
