The Optical Illusion in the Produce Section

Grocery stores sell fruit in mesh bags because it's to their advantage for you to buy twelve oranges when you only need two. If the last few oranges go bad before you finish the bag, then you'll go buy more. You might even find a couple have gone bad as soon as you open the bag, because you can't inspect each orange in a five-pound bag before you buy them. They looked so good when you picked them up, and some of that is an optical illusion.  

However, it's all relative. Oranges with some green in them can still be perfectly ripe, but Americans won't buy those, because you can't really be sure. Our best strategy is to try different fruits from different stores and go back to the food vendor that delivers what you like.
