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."
