Afaik bodegas make most of their money from cigarettes and booze, so this is unlikely to cut into their income in any real way. As for grocery stores owned and operated by the people who work in them, there aren’t many of those but I would expect they’ll be aware of that and open these gov stores far away from small local grocers (who tend to have cheap food already).

As for people who own grocery stores and don’t work in them? That’s an investment not a job, gov has no duty to protect individual investments over people’s basic needs.
