McTrashcans

Where I live is quite common to see such a spectacle.
People park in the area (behind the fast food, and in front of my house!), eat their "happy"meal, and just throw bags and boxes on the ground.
It seems to be an education problem, and actually it is, but just in part because in the entire area there are no trashcans.

McDonalds could face the problem, acting on the pack, on the "drive away" section of the fast food, and... probably placing some (branded) trashcans where people go to eat BigMacs and cokes.
It could be useful.
