Playing double-devil's advocate:
1) Most people have no problem buying ugly food. Much of the standardization of produce comes from packaging and packing requirements. Non-standard produce is still consumed in other forms: juice, frozen, soup, etc.
2) The vast majority of food waste comes from unsold restaurant food and food that goes uneaten at home (goes bad before you can consume it). This has nothing to do with ugly food.
3) The bruised part on apples tastes like crap. It's mealy and sour and fermenting and off-flavored. It's not my responsibility to eat bruised apples because a store can't be careful in handling. Blame the supply chain and grocery staff, not consumers.
