The saying “There is no such thing as a free lunch” apparently does not apply to Madline Nelson, a New York resident, who calls herself a *dumpster diver - people who collect food from rubbish bins. But don’t go thinking they’re *vagabonds or beggars; most dumpster divers have legitimate jobs. The reason they go through other people’s trash is to act against food waste in Western countries. Plus, often there really is good food to be found.
