Unfortunately the hot plates that keep coffee warm also cook them, so you’re a bit behind the eight ball. If you haven’t, taste the office Folgers fresh vs sitting on the hot plate after two hours. I’d rather have the fresh Folgers over pretty much anything off a hot plate.
To answer your question, the Kirkland stuff is definitely better and not that much costlier than Folgers if you just want a momentary reprieve from the dirt flavor. I will gladly drink that fresh off an okay drip machine, even pre ground.
While the hospital won’t buy the coffee, could you buy through the hospital? Your food operation might have access to something better than Folgers at similar or better prices. I know all that can be wildly complicated, but likely worth a five minute email.
You can contract a commercial entity as an office. I imagine hospital break rooms go through a lot of coffee. An office contract would see to someone delivering coffee (and maybe getting equipment possibly including a coffee urn which would make an enormous difference), taking it off a rotating schedule and making it as simple as everyone dropping a buck in the coffee bucket every two weeks. I don’t know how in you are with whoever would greenlight that, or how much effort you’d like to put in, or how game your coworkers would be to try something new. It can be very reasonably priced when you buy enough coffee.
If those two ideas are too much work, they’re too much work.
You could also do the selfish thing and bring your own beans and an Aeropress. It has the highest ceiling at the cost of being That Person. I also personally really like Cometeer’s pods, which are way more expensive but discrete.
