Those were some pretty crappy "snacks" too, but to each their own. I find that portion sizes are quite reasonable, at least as labelled here in Canada, and totally satisfactory. A serving of ice cream, for example, is half a cup, and generally runs 120-180 calories, depending on flavor and richness. Even if you need a mountain of it (a full cup, two servings), it is totally manageable to make space for it once or twice a week. On the more healthy side, a decent sorbet (Chapman's) runs 60 calories a serving, you can have that every day if you want. Whether Doritos taste good or not is a matter of taste obviously, but they are pretty much the worst calorie and nutrition-wise out of all the chips. There are tons of better choices out there, like veggie straws or chips and salsa. Cookies (whether Oreos or oatmeal cookies or biscuits) generally are 2 per serving, and will run 100-140 calories, a nice occasional snack to go with an evening coffee or tea. Serving sizes are very reasonable (at least in places where they are required to be by law, none of this "only 10 calories per serving!" crap) and the label is there to help people make informed choices. If the fatties don't care, they are free to ignore it and eat the whole bag or two as a serving. It would be nice though if serving sizes were more standardized, for example yogurt and cereal will often use different serving sizes, even within the same brand, making comparisons needlessly difficult.
