Do your parents still see them as a luxury and not buy?
I'm 42 have dh and ds 9 and we generally get a meal delivery every week.
Money isn't an issue for my dp as they are comfortably retired.They will go and pick up fish and chips from time to time but no eating out in restaurants as a couple or chinese/indian/pizza etc.
Mil is the same
A generation thing or just different strokes for different folks?
