I used to work at an investment firm (just three years ago) in the accounting office which was located next to the lunch room where they had social gatherings.
Once a month they'd have a "social hour" where investors could come up and enjoy a beer with the team.
I partook once, but decided against it after that.
Just wasn't my style to socialize with co-workers...felt really weird.
I also didn't care for their selection of beverages (If I'm gonna put poison into my body, it at least has to be higher quality poison).
Reminded me of advice I was once given:
"Don't
where you earn a living"
