I live in one of the biggest cities in Oklahoma, so its no New York City, but there's a lot of people here. It's a safe bet that 1/3 people here with a backpack are in fact stealing, which I can validate because I've seen it. To be clear, they're largely stealing food, clothing, diapers, or medicine, and never once have I judged them wrong for it. But they are stealing, and as such it's a reasonable policy for the stores here. Maybe try to avoid major corporations in smaller towns? They're the only ones who really care about Danny stealing a Vienna sausage for his kid.
