Is this really that infeasible? If we just started somewhere unhealthy, and said In N Out with drone delivery, then the $5/meal isn't that far off from what the current cost is.

If we could eliminate the building, the employees (and all of the overhead that goes along with them), and the expensive location that the buildings are usually in, it seems like the cost of the burger could come down.

That sounds pretty nuts, but I don't think it's completely impossible at scale.
