Let's go to the ad agency press note!
"In order to dramatize the bad eating habits in children, we designed child-shaped trash cans and placed them in shopping malls and food courts across 10 cities. (They) were also placed in parks, schools, and high-traffic streets. A child-shaped garbage truck also drove across 55 cities in Puerto Rico."
How I read this ambient stunt:
"Subway is garbage. Feed Them Better."
