I am offended by the dishonesty of serving sizes so much that I will refuse to buy an item because of it. If I buy a cookie, I'm probably going to eat that cookie. Do I care how many calories it has? How much sugar or carbs? Probably not. But if I see that it only has 130 calories, maybe I'll be persuaded to eat the cookie.
Wait. What's the serving size? A quarter of a cookie. Ok, it's a big cookie. But I'm still going to eat the whole thing. I'm not going to break it in half and in half again to satisfy some sadist's view of how people actually eat cookies.
Can this get any worse? It was in a bag with 3 other cookies. So the nutrition label said there were 16 servings in the package.
