My Mom couldn’t watch that show because she realized she had some kind of PTSD from having been a secretary from right out of high school in 1956 (until she retired in 2003), that the patriarchy and sexual harassment etc. is totally factual, even watered-down from actual reality of that period.
I was in Advertising for many years, and the epic levels of drinking (also depicted in Augusten Burroughs’ “Dry”) was also factual.
