I'm a little young for this exact conversation, but Feel I have something to add/share.
I feel quite fortunate to be among the last to work in a full service porcelain gas station. It was owned by, and named after an ornery old man Sam Shull. This was confusing, because it seemed like it should have been a Shell. Maybe it even had a shell symbol somewhere, but it was absolutely "Sam Shull". His son Ronnie, who was a bit touched, ran the pumps. Then there was the mechanic, Barry. Half Bob Seger, half Smokey Yunik, Barry was a friend of my Dad's.
In rural Tennessee, outsiders gravitated to one another. My Marylander Dad, and Michigander Barry were fast friends in the early 70's. To complete the blasphemy, they both were into VWs, had long hair, as well as beards and/or moustaches. Not well accepted in the area.
Dad died in the early 80's, and I graduated in '89. Barry probably felt some responsibility to teach both my older brother, and I something. So summers between college in the early 90s, I worked in a full service gas station, too naive, and sheltered to realize this business was soon to go the way of the liquid lizards Ronnie pumped into those folk's tanks.
Barry taught me a lot. A lot about cars, and a lot about life. His mantra of "If you can't do it right, ...Do it Wrong" is repeated nearly daily in my polluted gray matter. "Leave well enough alone" is another of his gems. His laments of "Ronnie is SO stupid!" are echoed when I have to deal with people I I feel could maybe do a bit better. He paid me somewhere around $100 a week, which was great money back then, but in retrospect, I feel I should have been paying him for the real world education he offered. Frankly, as a college dropout, he taught me much more than any professor.
The great thing about The Station was the cast of characters that were constantly cycling through. The Jr. High Ag teacher was a regular- son in law of Sam, as I remember. Across the street, was a Hardees, and we would marvel at how they would serve a seemingly endless line in the mornings. Biscuits were king. A lawyer's wife would get her dog a burger every day. I kid you not, but Haskell was my favorite. He lived maybe a half a mile away, and walked by to see us daily, it seems.
A scientist on the Manhattan Project, "The Assassin", as people would call him behind his back, was a nice old fella. Like some sort of sit com character, He'd enter the shop daily, and declare, "Boys, I'm the most miserable man in Warren County", and one, or all of us would dutifully reply, " Why's that?" He would respond with admonitions of what a horrible, brow beating, unreasonable wench he had married all those years ago, and how she seemed to only delight in hanging on one more day to torment him, weather financially, or with some more clever and devious degradation, the only solace from which, he was currently experiencing.
The funny thing is, he loved her. We all knew it, and so did he. After he died, I got a shoebox full of his old glasses. I had my prescription lenses fitted in them for years.
Largely, we worked on imports at The Station. We'd fix anything, and I later learned that Barry's billing was largely on a sliding scale. If someone was in need, they were charged what they could afford.
Integrity. That is my take away. Barry went through Viet Nam as a very young man, and no doubt, had demons to battle, but he chose to live simply, help when he could, and laugh quite a bit. He's still with us. I need to drop by his shop.
