Came here to say this. Expanse hits the notes of "real people actually live on this ship/station" way more than any other sci-fi I've consumed. Fast food, bars, brothels, restrooms, storage and maintenance areas, all of these are specifically called out at most stations.
I noticed this too, The Expanse does that so well, really fleshing out what life would be like living as a grunt in The Belt. They had their own culture, their own sayings, their own food. Like any colony, it gave host to any number of establishments meant to provide a bit of comfort out in the inky black nothing. The shared suffering also gave them a sense of community, which is a powerful motivator when the far off motherland starts imposing increasingly burdensome levies... Makes you want to grab the closest thing and hurl it at them! 😉
