The "obsession" is that it's local, with all that entails: It stocks what the customers need/want, the owner knows a lot of those customers. IOW the "obsession" is that the bodega is part of the fabric of the community in a way that a corporate chain store hardly ever is.
The size of course is a function of real estate cost - so if you're looking at something larger, it's gotta have either higher margins, more volume, or both.
