I can't imagine people being addicted to it. I see fast food as a rare indulgence. A bad treat. It's terrible food, terrible for me, and while it tastes good while I'm eating it, I always feel a little sick when I'm finished. I guess I feel obligated to eat all of it.
When you eat unhealthily all the time it's just normal and you get used to it I guess. It'll be at least another 5 years before I go again. And then I'll just go in and eat there and watch the robots prepare everything.
