Here are a few more "oldster" things to remember:
Tube testers. These were machines at various stores - hardware stores, Woolworth's, even Walgreens - where you could take vacuum tubes in to be tested. You set adjustments for voltage, load, etc. , on the type of tube you had and if the meter said it was bad, you'd go into the cabinet below the tester, pull out a new one, then go pay for it at the register. ("What are vacuum tubes?" some may ask . . . vacuum tubes are early electronics, commonly used in televisions before transistors and solid state circuitry.)
Dime store lunch counters. I remember some of the best hamburgers & fries I had as a kid being served at the lunch counter at Woolworth's . . . even the Heinz Ketchup tasted better than "store bought" Heinz Ketchup. But then along came McDonald's . . .
Riverview Amusement Park - probably means nothing to you unless you grew up in Chicago. But I've noticed even the traveling carnivals with attractions and a few rides are becoming rare.
Gas stations with service and premiums - there was a time - not all that long ago - when most places selling gas also did mechanical work on cars; these places are few and far between now. They also used to give you a premium - box of Kleenex, a drinking glass, or something of the sort - when you'd fill your tank.
Banks with premiums - same thing; if you opened a new account or made a deposit, you'd get some sort of gift; a new toaster, a set of steak knives, usually something for the house.
Guns at Sears . . . they were in locked racks, but just in a regular aisle in Sporting Goods, not even behind a glass counter. They even had a house brand - "Ted Williams" - that they advertised heavily. The selection got smaller and smaller and eventually disappeared altogether. (Again, this was at a Sears store in
Chicago. Montgomery Wards and, IIRC, JC Penny also sold guns . . .)
Gaaahhh! I'd forgotten just how much we've lost . . .
