Yes. Occasionally I'll get an order of fries (with my weekly under-500-calories burger-and-fries meal) that is only like half full. I just hand it back to them and ask politely if they can fill it up, please. They do. No problem. But fats have to scream and throw tantrums everywhere, because they're basically infants--or rather, they are people with all the selfishness and greediness of infants without the sweetness and innocence and adorableness and all the other things that make us put up with the "bad parts" of infants.
