We have absolutely enormous parking lots, and yeah, Americans are lazy and have an abundance of food. Maybe not more inconsiderate, but Hanlon's Razor comes into play here. If you don't believe me, just go to any Golden Corral. There absolutely will be multiple families in there where every single person weighs over 250 pounds, even the 8 year old kid.

I remember a girl in highschool that was an exchange student from Botswana(?) was a bit upset that she was too fat to go home after living here for a school year. She'd gained like maybe 5 pounds. As far as all us Americans were concerned she finally didn't look anorexic.

My brothers and I would run around the parking lots gathering up all the carts rather than go into the store. This was especially fun at Aldi's cause we got a quarter for each cart, and could get some candy.
