Try spending more than an hour visiting every produce store in your (hypothetical) town to find a loaf of bread because they all out of stock by mid-morning, and than tell me that a well-stocked supermarket near by is of no use.

Try going to your free dentist for a filling and have their drill bit break in half while inside your tooth.

Lastly, quality of many food products available outside of major cities was not much different from "petroleum-based cheese product".
