Yeah, so you can be mugged and robbed on your way back home. Don't think there wouldn't be individuals scoping the store out, and waiting outside to follow you to take what you just bought, along with everything else on your person, and perhaps even your life.
Actually, you can probably get your fill just breathing deeply on a number of streets in Harlem. The northern border of Marcus Garvey Park, a few streets to the east, being one example of where one can freely fill one’s lungs.
