Pre-COVID it was very interesting sitting in a bar in downtown SF and listening to all the drunk tech workers mouthing off. You could hear a lot of illegal activites, particularly racist or poor hiring practices, boasted of or complained about very regularly.
I liked Mikkeller for this, but it got too loud. Irish Bank was also good, slower but quieter. I used to nag my friends about opsec... back when you could go places with friends :*(
