It's more like:

There are 2 grocery store chains in your city and zero restaurants or other ways to get food not owned by those chains. One already has a supply of only expensive, big-brand products, with nothing organic and very few healthy items The other chain has more independent items that are healthier and more reasonably-priced, as they allowed smaller companies to sell there. Now they are closing the door to these smaller companies, making them appear as a clone to the first chain.
