I’m assuming that you grew up in a relatively small town, and long enough ago that such things weren’t common. It’s no big deal if you grew up in New York City and had a MacDonald’s. But in my circa 17,000 person town in the 1960s we didn’t have one (that was for the town next door, which had a major highway going through it).
Ben Franklin’s – a 5 and 10 that’s still around, although as a hobby and craft store nowadays. The one in my home town closed in the 1980s.
Acme Supermarket – there was also one on the highway in the next town over, but this was a smaller one right on Main Street. They still have over 150 stores in the Northeast, but both of these are gone from where I grew up. For years I wondered why I couldn’t find Rocket-Powered Roller Skates or Earthquake Pills there.
Rexall Pharmacy – the company virtually disappeared in 1977, although the name continued to be licensed. Our pharmacy that was a Rexall is still around, although it’s passed through multiple owners, and is no longer Rexall.
Banks and S&Ls – Not big chains, but some local banks and Sacings and Loans had branches on Main St.
Convenience Store – one local-area convenience chain had a store on Main St., even while the Acme was still operating. Now the Acme is gone and the convenience store is operating on part of their premises.
There were a few franchised gas stations – Mobil, Chevron, Shell
That was it Things have changed
Now
Dunkin’ Donuts – right on Main St.! Still amazes me.
Bank of America – this and a couple of other banking giants had bought the property or acquired the bank that used to be in the big banking temples on Main St.
Wawa – this convenience store moved into a couple of locations in town (but not on Main st.)
The big drug store in town – which was privately owned, got bought, then moved out of downtown to the edge of town, then repeatedly bought by other chains. It’s now a Walgreen’s, and probably the largest franchise or chain in town
There are still franchised gas stations, but they’ve changed. Chevron’s gone, but we have a BP.
But that’s it. No MacDonald’s or similar fast food joint. We still have local Pizza parlors (no Domino’s or Papa John’s or Pizza Hut). No 7-11 or other convenience besides Wawa.
It’s not “small-town authenticity”, I think the big businesses figure the town is too small a market with inadequate access and parking, so they stick to the nearby towns with highways.
