Effective and Clean Way of Getting Rid of Someone

The lunch kept on going for a while longer after Ford had come back from cleaning up in the rest room. He made sure to place a napkin on his lap this time and make Moon suffer for what she allegedly 'accidentally' did. 

When he came back, surprisingly he was sporting cheery mood and a smile that spoke nothing of his inner fury. Moon reckoned him either a very good actor or herself to have misjudged him for being a bad tempered jackass. 

Perhaps he understood it as nothing more than an accident and chose not to hold a grudge. That smile sure said it but what he did made her realize he definitely went for the getting even approach rather than boiling his own blood dry for vengeance.
