I was referring to the rank and file crew, not Our Heroes. But even with the above examples, only two apply (since the others are off ship): Uhura and Rand. And both of those were in their own quarters.
I'm just pointing out the The Cage and Where No Man Has Gone Before featured scenes intended to show the crew off duty and relaxing out of uniform and we never saw that sort of thing again. If it weren't for TNG I probably would never reach the conclusion that any of those people might be civilians.
