I'm old enough to remember when the 'no laptops' signs sprouted and then quickly were overwhelmed or went out of business. I didn't take it personally - by that point I understood that my gf and I making graphics and websites while talking to the regulars wasn't the problem. Most of what I'm referencing is in South America, Thailand, Vietnam, France, Czechia and Spain. Generally liquor licenses are permissive and they're family owned, so, a lot of places serve coffee during the day and transition to bars and nightclubs at night. There is a general flow to your day where as evening approaches, you switch from corfee to alcohol and people you know come and populate your table, sometimes they work and if they're coders you talk shop about databases or something, then it gets too loud so you go out with whoever came by and get dinner. And if the server is finished you invite them too. This is what I considered a
civilized form of working in a cafe with a computer on your table. And even at that,any times my gf thought it might be rude so we'd put it away and play chess or read.
I think if people had an awareness of their surroundings in these spaces, the spaces wouldn't have turned into sterilized off-campus work sites. But that may be asking too much from people who've never experienced it. I think this is what some of the 90s/00s startups were trying to replicate with their play rooms, but that's a far cry from sitting with a local dev and a taxi driver and a drunk musician spitting out ideas To me that's what the cafe is for.
(edit) I don't mean this to come off as the rant of an old gen X-er... it sounds to me like you had a real appreciation for the counterculture of ideas that could bubble up from having some limits and creativity in those spaces. You woulda loved the 90s. But maybe if enough people get sick of Blue Bottle Coffee and Starbucks, we can claw some humanity back. As it is, the less work-centric and more friends-and-family-centric parts if the world mostly reject the cafe as workplace model. They didn't used to find it so rude but they do now. I hope we have a backlash in the States if only because people really need that space to be verbal, interacting humans with each other. Especially on a lunch break.
