Pay The Price

A man walks into a bar and says, "Excuse me, I'd like a pint of beer." The bartender serves the drink and says, "That'll be four dollars." The customer pulls out a twenty-dollar bill and hands it to the bartender."Sorry, sir," the bartender says, "but I can't accept that." The man pulls out a ten-dollar bill and the bartender rejects his money again. "What's going on here?" the man asks.Pointing to a neon sign, the bartender explains, "This is a Singles Bar."
