I don't remember them at all, I started flying after they'd gone. Which is sort of why I'm asking this question in the first place. I've never experienced the "glamour" service of the past. And flown too little in the present to contrast it with even if I had.
I'm sure SOPs now and then don't differ all too much. But I'm still very curious as to what did differ. Times, technology, and service level was different after all. How were duties divided (BOAC had purser, steward one, steward two, and three ladies according to a short documentary retelling service in the 60s is to believed)? What were normal routines (There was less entertainment, but more involved catering etc)? What were common ailments/complaints from passengers and how were they treated at a time without the medications or service level we expect today? Etc. etc.
