Yes true, but what I was aiming for is when people don't like some/take too much food and then they trash it. I have been raised to never throw away food on my plate. Also if I commented and said I didn't like some certain food, they gave me more and I HAD to eat it.
So if people take too much food, they should overeat just to avoid wasting food? It'll go bad anyway. Who cares if it's sooner rather than later?
