FPSJ - that's not disordered at all, it's good as new. Think of it this way, if someone came over and left some unpeeled fruit at your house, wouldn't you see it as "fair game" or a "bonus?"
besides it's normal to think "man don't waste perfectly good food." I remember going to a wedding with my bf that had the best cake we'd ever eaten, and both of us being really angry that the (skinny, naturally) chicks at the table next to us only took a couple bites of their big slices and left the rest.
