It's an interesting question, though it is somewhat suburb-centric.

In NYC, the elderly and disabled have no natural access to these kinds of services unless they live a block or two away from such an establishment, for the simple reason that hardly anyone living in NYC owns a car. Yes, they can take a cab, and that makes it feasible, but economically speaking, the most common outcome is these people are dependent on the bodega on their block to provide their food.
