"When we all worked 9 to 5 in the office"

I have never worked a 9-5 job. I have always had non-standard shifts such as 07:00-15:30 or 17:00-01:00.

Now a typical shift for me is 07:00-17:00, but even then I'm normally working somewhere other than my "home" area, so there's still very limited hangout time.
