People smoked everywhere. The office, restaurants, shops, church, in hospitals, theatres, government agencies, on trains & buses, in a taxi, in a supermarket, etc. Try explaining that to a millennial.
Church is one place I don’t recall ever seeing anybody smoke; but all the other places, yes. In the early ‘seventies, we smoked in university lecture halls - and a lot of the profs were smoking while they lectured.
Not that I think it was a good idea; but it’s interesting to see how demonized it has become - people are even afraid of it in the open air, while big trucks and buses roll past them spewing exhaust ;-)
There is a refinery nearby that still has the old fashioned bathrooms with the old fashioned ashtrays in the stalls.
Remember when even the fitting rooms of department stores had ashtrays?
When I was little I fell and split my knee open when it hit a sharp rock.
My doctor smoked the entire time he was stitching me up.
I was afraid the ash would drop right into the wound.
And almost NO child had asthma nor a peanut allergy back then.
