Exactly. I like the idea of "traditional American supermarket" for the irony content.
When I was a youngin', our town didn't have any chain stores, just a dozen or so family markets.
I miss the culture and environment, not so much the lack of selection. Since then, it's hard to take sides in a Safeway vs Walmart vs Amazon brawl.
The first chain fast food (aside from the ubiquitous Dairy Queen) came somewhat later. That's a thing I think we could do without.
