Historically, social clubs were a thing!

You've got gentlemen's clubs of the kind that Phileas Fogg from "Around the World in 80 Days" belonged to. They were leisure spaces where the rich could socialize with each other, dine from a wider menu than their own domestic staff could offer, access a bigger reading library, and organize group activities like automotive clubs and regattas.

Then you've got private societies like the Freemasons and the Rotary Club, which were usually segregated by gender and race, had a religious component, and offered services like mutual aid and insurance.
