Why is it that when you run a system in a family home for a few years other occupants cant seem to stick to it?. Why do said occupants have to go against what has been proven hundreds of time over, yet feel that they dont need to follow this proven method. Geez it is not hard! Cups dont go between to bowls in the dishwasher!! Because the bowls dont get clean properly if they are not loaded correctly. Cup go on the outer edge of rack where they are designed to be housed for washing. Water jets go up! Grrr.!!
