People who do their grocery shopping in public trash cans, dumpsters, etc. It's not only homeless people who forage through these kinds of dumpsters (usually grocery stores and restaurants bins) but also a growing number of people with low income. They find un-eaten foods (usually spoiled) in public trash bins and take it home with them just like store baught items. Benefits include, free food, waste reduction, and some health benefits from consuming slightly spoiled foods.
