for what its worth, some feedback I got from a guy I know on another board:

I'll just offer my two cents as usual...if anyone else wants to add a comment great.

Over the years I'm been acquainted with a few producers that had stalls at farmers markets.
They would pay for their tables and sell their products every week end. As well there were a few actual farmers I would deal with for donations of excess produce for the food bank I managed for several years. Since then, a few have sold their land or retired.
A couple of others have gotten really big and supply the major chains.
They have had to compete with huge food importers that have had long term contracts with the majors for decades but they succeeded by offering local quality product, good pricing and the volume to meet orders.
That is part of the key to be able to supply large volumes of produce consistently to the majors for them to even take them seriously. They still have to pay for shelf space and all the associated costs, shipping,
stocking etc and had to synchronize their inventory/data/software system with the majors.
Bottom line is it's a brutal business and cost big bucks to be able to even compete. The few remaining and widely scattered
"mom+pop" operations would kill for an innovative joint venture with major gas retailers but it would really take a lot of marketing+serious promotion to get something like this off the ground.
For instance who in their right mind would think, currently of going to a gas station to pick up their salad greens?
I know where you are going with this.
As a hypothetical owner of a gas station that over the next decades see their revenue dropping as EV's and
hybrids become the norm, how do they revitalize their business and create additional revenues? After all most stations are independent franchisers of of the dominate fossil fuel suppliers.
First, I would hope that they would increase their (as you put it "paraphrased" garbage food) selection
to better quality options, add EV charging hubs, an adjacent outdoor/sheltered dining area for their ready to eat
snacks... perhaps a few pick nick tables and a greener ambiance (with lots of trees...lol ) near by.
If they had the where with all, they might even offer/build or create an association with established nearby motel/lodging for travelers, tuckered out needing a break and an over night charge.
Perhaps cooperate with a major restaurant chain for breakfast dining.
Most gas chains became defacto corner stores years ago so it's possible that they would be open to collaborating with local growers for them to be able to offer their produce at charge/fuel locations but again it's got a lot to do with public perceptions and produce turn over. Stuff has to be super fresh and no one waiting for a charge is going to stock up on wilted lettuce or a bag of soft sprouting potatoes when they can stop off at a Walmart or whatever on the way home.
Perhaps a good approach is to have cooperation with a produce stall/farmer close by but on the same lot,
This could be a good start and easier to set up with smaller independent suppliers that believe it or not are still around.
Plant the seed of that cooperation and if it takes off the major gas retailers would jump on board.
