There is a whole subculture of those that dumpster dive for food; they call themselves “Freegans”.
Some just do it for the cash, some because they are nutty libs who believe we live in a wasteful culture. One of the contestants on Project Runway this year was a “Freegan”.
My guess is they found a few of these for their photo op. They’ll manage to find a lot more if Romney gets elected.
I know a lot of people who do that.
