In his eyes, Nancy has entirely missed the point. It's not that Cooper had acted so poorly (Cesare will sort him out later), but the fact that Nancy was in that situation in the first place. She had paraded herself in his establishment in an exceedingly unprofessional way. If she wants to act as if she doesn't value her job or take pride in her professionalism, he is happy to treat her as such.

He's about to speak when there's a knock on the door and in walks a brunette teetering on platform heels. She apologizes for being late and promptly sits herself neatly on Cesare's lap. He smiles at the girl and absent-mindedly traces his thumb up her neck before looking back at Nancy.

"I appreciate that. Is that all?"

Nancy can try to make herself as appealing to Cesare as she wants, but if she's happy to show that their professional dynamic isn't important, then he's happy to do the same. There have always been other girls. He's just tried not to parade them in front of her. Now there's no space for such courtesies.
