Yup, change in behavior... cooking in someone else's kitchen, buying a BIG freezer, using someone else's meal plan/menu, which may mean new food the family might not take to right away! I can see it being a big help for large families, also when preparing food for an event or party, or just having stuff made in advance if your life is going to make it hard to cook every day.... illness, company visiting, etc. An alternative for certain occasions or times of the year, not necessarily doing it every week.
