Buddy,
Also included in a fill-up were the cleaning of your windshield, free maps, checked your tire pressure, still no charge, and check your oil and antifreeze as well as your windshield washer pump for fluid. Oh! Transmission fluid as well. Every once in a while I see a station advertising full service. I don’t really think they know the definition. All the above were done free for the less than $5.00 fill-up. They even had clean, stocked restrooms you were welcome to use, even if it was 10’ outside and the restroom was behind the station. lol Yes, the good, the bad and the ugly of it. Of course, I’m talking about the mid fifties and sixties.
