Taking Care of Business

A man walked into a cafe, went to the bar and ordered a beer. 
“Certainly, Sir , that’ll be one cent.” 
One Cent?” the man exclaimed. 
He glanced at the menu and asked: “How much for a nice juicy steak and a bottle of wine?” 
“A nickel,” the barman replied. 
“A nickel?” exclaimed the man. 
“Where’s the guy who owns this place?” 
The bartender replied: “Upstairs, with my wife.”
The man asked: “What’s he doing upstairs with your wife?” 
The bartender replied: “The same thing I’m doing to his business down here.”
