"Excuse you?" But he backs up a couple of steps, still ready to hit fight mode if necessary. "I mean, I don't owe you shit, but that's fine. I can always leave you to the guy." He takes another step back to make his point, but with enough weight on the balls of his feet that he'd be able to manoeuvre himself quickly. He continues "see how well you eat and how long you last on scraps if you don't pay the guy. Place like this? Word spreads fast. Some manners might be a good idea."

He's like 90% sure this guy ain't playing with a full deck.
