[The Expanse] If water on Ceres is so valuable why are steamed and boiled foods so common?

Detective Miller frequents a bar where they're constantly steaming something like your typical sci-fi ramen stand. If water is "more valuable than gold," heavily rationed, and constantly fought over why is this restaurant owner so cavalier with its use? Shouldn't they, at the very least, have something set up to capture and reclaim the water vapor?

I don't imagine the answer to this needs spoilers, but just in case please limit them to S1.

A chunk of ice the size of a skyscraper is more *useful* than a chunk of gold of the same size.  
  
Humans need a lot of water, wherever they go, but it's not like the water is "used up" in the cooking. Everyone in space lives inside of a pressurized capsule surrounded by vacuum... so the water will eventually be reclaimed. They need all that water for, presumably, cooking noodles and boiling eggs.
