My grandmother used to be a big city office secretary back in the late 1950s and early 1960s when she was in her 20s before she became a housewife and she has told me that most people smoked in the office back then and it was very normal.
She said her boss usually smoked two to three packs a day just at the office and that she'd have to empty his ashtray several times a day and also bring him a fresh cigarettes anytime he asked for it. She said she was expected to keep at least two cartons of cigarettes in her desk drawer for him so he didnt run out, and that she was told to order his cigarettes just like ordering office supplies for pens, paper, staples etc. He also told her she could order herself cigarettes when ordering his, and as long as she smoked the same brand he did, she could smoke all she wanted while at work.
She also told me that her boss drank often at work, and that he kept both several bottles on a bar at the back of his office and that he also kept a bottle or two in his desk. Again, she said hed have her order bottles for him to keep in her desk as backup. She also said that it was not uncommon for the guys to go out for drinks after working late, but also that on more than one occasion her boss would take her out to a fancy dinner in the City, just the two of them, even though he was married to another woman.
When I told her how strange that seemed now, she just laughed and said I would even recognize the workplace, especially with all the sexual harassment suits and stuff now. That was of particular interest to me since I had been the subject of sexual harassment at the workplace recently, and I asked her if shed ever been harassed. She said "not unwillingly" and proceeded to tell me about how she used to sleep with her boss from time to time. Yikes.
