Wagner's MBA Law of Getting Your 80-year Old, Great Depression Era Parents to Eat

Wagner's MBA Law of Getting Your 80-year Old, Great Depression Era Parents to Eat: Always show up with 3 Gallons of Milk, 3 Loaves of Bread, and 3 Dozen Eggs, etc., and say, "Oh, you don't want this...?! I guess I'll just have to throw it away... or you can throw it away when it expires...!" They'll EAT IT ALL or at least try not to waste ANY of it.
