In TNG, Picard says that the Federation has evolved past a need for money. Indeed, we never see any.
In DS9 though, Quark talks a lot about bar tabs and costs. Surely O’Brien and Bashir don’t get free drinks, so how do they pay? I’d assume that any Ferengi worth his lobes won’t accept anything that can be replicated, so do Federation officers get a stipend of tradeable “value” when interacting with cultures that still expect payment?
I think there’s also a reference to Quark paying rent to Sisko for running the bar. Presumably that’s denominated in latinum. I wonder where it goes? Maybe the secret “Garak black ops” fund.
This leads me to another thought: are station residents charged for using the replicators in their quarters? I imagine the replimat charging like other station businesses; so what about private replicators? Or maybe I’m wrong, and the replimat is a free public service?
I’m guessing replicator use would be free under Federation jurisdiction the same way Quark isn’t charged rent. But on the other hand, it’s a Bajoran station - Starfleet only administers it. Now I’m wondering what kind of negotiating went on to get the struggling provisional government to pass up revenue from DS9 rental spaces.
@hallettj The replimat is probably free. They likely don’t set up account for every Skreea. It’s just the public replicator place.
