"False Economy" joke

A man walks into a bar one night. He goes up to the bar and asks for a beer.
“Certainly, sir, that’ll be 1 cent. ”
“One penny?! ” exclaimed the guy.
The barman replied, “Yes. ”
So, the guy glances over at the menu, and he asks, “Could I have a nice juicy T-bone steak, with fries, peas, and a salad? ”
“Certainly sir, ” replies the bartender, “but all that comes to real money. ”
“How much money? ” inquires the guy.
“Four cents, ” he replies.
“Four cents?! ” exclaims the guy. “Where’s the guy who owns this place? ”
The barman replies, “Upstairs with my wife. ” The guy says,
“What’s he doing with your wife? ”
The bartender replies, “Same as what I’m doing to his business. ”
