Even though Suri would've totally deserved this, I actually see it more like Coco telling Suri off like this-
Suri: Coco make yourself useful and go get me another cup of coffee.
Coco: Um no.
Suri: What did you say?
Coco: I said no Suri, If you want coffee you can get it yourself because i quit.
(Coco walks away with her head held up high)
Suri: Fine, I don't need you. But good luck, You will never make it in this town without me.
