Making friends mostly at work causes a lot of consensus bias related to economics because it means less exposure to people who didn't get as lucky with any part of the process of getting that job
I always wanted a job that was like sitcoms based around work, where everybody is friends and hangs out. One time a building contractor moved in across the street and had his crew there for a while remodeling the house. I noticed four or five guys sitting at a picnic table in the front yard with beers, and I thought wow, so cool that the crew socializes on the jobsite after work!
It turned out not to be exactly like that - the two women in the rental next to my house were shooting porn in their garage with the door open, and the line of sight was from directly across the street where the guys had their table.
One time I was in the driveway when a car dropped off one of the roommates wearing a United Airlines flight attendant uniform. So I assumed she was a stewardess, but on second thought maybe it was a costume lol.
