“Has he ever seen the size and thickness of a candy bar pre-1970s?”
I have, I entered first grade in 1950 and when I had a nickel I could buy a candy bar that was all I could eat. You didn’t buy a ten cent candy bar unless you were going to give half of it to someone else. I paid five cents a day for school lunch when I started school. It was only up to a quarter a day when I finished high school. Now the dollar and a quarter I paid for a week of school lunches my senior year won’t buy what used to be a five cent candy bar.
My father in law told me a D-bar (a huge, mega thick Nestle’s candy bar) saved his life in WW2.
He was in a fire fight with a German. They both stood up hiding behind something and fired at each other at the same time. The German’s bullet hit the pocket with the D-bar, converting it to “coca powder” and deflected off. The German apparently wasn’t as lucky.
