There's some fine acting in this episode. Acting like there's nothing they can do to save Sulu from freezing to death on the planet below, for one. He even explicitly mentions beaming down some hot coffee, which the crew just seems to ignore.

I suppose if it got duplicated it might split into a decaf skinny latte and a double espresso.
