Reminds me of this 2014 article about a "standoff" between McDonald's Employees and elderly Chinese people using it as a community space http://www.nbcnewyork.com/news/local/McDonalds-Elderly-Senio... Also, chess players being evicted from a Vancouver mall after 50 years of congregation http://www.timescolonist.com/chess-players-offered-new-play-... I have an ideological axe to grind here, but I can't help but think…
In what way are they better than private spaces? The main difference is that people can use public spaces for free, but only because the cost is borne by those who don't use them.
Meanwhile, using such facilities carries a social stigma, because they are, by and large, only used by people who cannot afford to congregate in private spaces (bars, restaurants, coffee shops, gyms, clubs, classes, etc.)
This article demonstrates how it's possible for companies to provide de facto public spaces, at minimal cost (the cost of a coffee, or similar), in a mutually beneficial arrangement.
