How much are disposable plates and cups a part of your home life?

I have a friend who uses only disposable plates, cups and utensils in her house. I have another friend who, when she serves dessert, puts it on paper plates. In my house, and my parents’ house, we never use disposable anything. I keep a supply of disposable plates on hand, for rare occasions when I bring food to work, but otherwise, I never use them.

I am curious if disposable (meaning paper, plastic or Styrofoam) plates and cups are something many people use at home, or not so much.
