One could smoke!
I quit 20+ years ago, but I remember smoking while shopping at a grocery store.
A few years before that, it was acceptable for a pediatrician to smoke in his office while holding a baby. Yup.
My aunt reminded me that grocery stores used to have ash cans at the end of every other aisle at the grocery store!
I remember when you could smoke in public libraries and court hallways and even in doctors waiting rooms. Also, the back of the seats in movie theaters had ash trays on them for the smokers. You could be watching Bambi with 50 children in the audience and smoke all the way through the flick if you wanted. Nobody thought much of it in those days.
