I remember the first convenience store in my home town. Open on Sunday, and sold a frozen slushy-type drink. A first for both.
I remember when gas stations sold and pumped gas, but didn't sell water. Actually, NOBODY sold water. It was possible that the gas station might have a Coke machine (regardless of what it dispensed, they were all Cokes, as in, "What sorta Coke do you want? 7-up?") The gas station might also have a Tom's vending machine for candy bars and/or peanuts.
I remember betting nickels on whose Coke bottle had come from the furthest bottling plant (Cast into the class bottom)
I remember when people used to cut their own grass, when vans were used by painters and tradesmen, and everyone owned a 4-door American made sedan. That was clapped out after 80kmiles.
There were no video rental stores or nail salons. I used to save change to buy a box of Federal Hi-Power .22 LR for $.57 at K-mart. Guns were sold in hardware stores, and the American Rifleman had two-page ads for mail order guns, one in the middle of the issue, and one on the inside back page. I neighborhood kid had an HTG M3 grease gun we played Army with. Nobody wanted it because it was sooooo much heavier than the Mattel Tommy-burst.
