I think JohnnyReb can go back further than most, based on his last post!
Back in the day, you could get milk delivered to your doorstep. To keep it from freezing, the house I grew up in had a milk chute. The milkman put the full bottles in the milk chute and picked up the empties.
Speaking of milk, back in the day there was no such animal as "2%", "1%" or "0.5%". Milk was milk, even if it had cream on top.
Light switches had buttons rather than a flip-type lever.
Houses were drafty, because heating them was relatively cheap. Coal chutes, anyone?
Back in the day, wringer washers were the bomb. People actually had clothes lines and used them. When was the last time you saw anybody hang their laundry out on the line to dry?
Women wore dresses most of the time, not just to get dressed up. And wore those goofy hats too, especially in church.
Back in the day, shirts had to be ironed. There wasn't any of that "permanent press" stuff.
You actually got free stuff at the gas station, which also included a car repair garage. Remember the "ding ding" when your car actually ran over the air hose, alerting the attendant to come out and pump your gas, check your oil, and wash your windshield? Oh, and no such thing as credit cards at the pump, either. Cash or check, but who ever wrote a check at the gas station? S&H green stamps, sets of tumblers, and FREE MAPS.
