I used to live in South Korea and it was quite a sight seeing doctors standing outside with their patients (in hospital gowns, IV's etc.) smoking together. I imagine that's what it would have looked like in the '50's here in the US as well. LOL!
There's a scene in April Snow where the wife has awakened from a coma after a severe car accident. She's in a wheelchair and her husband is pushing it and when they get outside for a talk, she asks him for a cigarette. He asks her if the doctor said it was alright and she said yes. Surreal, IMO! LOL!
If you had been alive in the US in the 50’s you would have seen the doctors and their patients smoking INSIDE the patients rooms in the hospital.
