Sure, children are/were starving in Europe/Africa, but we can't send them our leftovers. Guilting people into consuming more than they want/need is unhealthy at a lot of levels. Repurposing leftovers into less tasty reheated dishes is not very Chowish/Maximum Deliciousness. Even at restaurants where food costs are vital, it makes no economic sense to spend $2 in labor to reduce food cost by $1. So can I say it proudly? "I am an American---I waste!'
