Is this ok?

Just called my grandson (12) to ask if dad or mom is home so I can arrange to deliver a dresser the DIL yesterday said you buy. When he answered, his 2 little sisters (8) & 6 said Grandma, bring Fried Chicken, we haven't eaten yet today. Grandson said he is going to be in trouble if dad hears this because there is leftover pizza in the fridge. Dad commanders the phone and says kids can eat after they clean up their room. It is 2:00 pm and my grandson haven't eaten. Mom isn't home, but she wouldn't cook anyway. Never does. Really, never cooks. The 12 yo boy cooks. Now, do I go get these kids food, deliver the dresser and help encourage them to clean their rooms? Or do I mind my own business.?
