Well, the Fable had what he wanted- the other man had drawn first blood. However, Jack had been anticipating something more along the lines of a fist to the jaw or eye socket, so when Sanji kicked him in the side, he was taken a little off guard.

"OW!"

He was forced from the seat and to the floor from the kick, doubling over slightly in a mix of surprise and pain. That little bastard sure had strong legs. Well, Jack didn't have time sit there and take in the hurting; he had some "self defending" to dish out.

Forcing himself into a standing position, he issued a threat ("You're gonna pay for that") and threw the Strawhat a left hook right at his ugly mug.
