I was smoking at 12 in France in 1999, I told tobacconists I was buying them for my mom. Pulled the same thing off in the states when I moved there 2 years later. And I was far from alone. These are far more recent (terrible, obviously) habits than you might think.
Yah, my uncle lived to 94, smoked for 89 of those years. Pretty sure if we'd had a nuclear war in the 60s, that fucker would have still made it into his 80s.
I think those might actually be frosted glass cups.
Here is the best copy I could find, and the flared edges do not look like plastic cups - also the shiny inside and matte outside looks more like glass frosted on the outside.
PP was not in commercial use until 1957 (not sure when it was first used for cups), PET disposable cups weren't a thing until the 70s. Disposable cups in the 50s would have been wax paper.
Me too, especially due to the use of the word 'ceased'. Reminded me of this video where a reverse scammer convinced the Nigerian scammers to record Monty python's dead parrot sketch, as he combines then he could get them a BBC grant.
