Laforge Rabbit, Data, "the Computer" and bolognium
The things characters do in a TV episode, of course, are limited by time and perhaps bugetary restraints on hiring good screenwriters.
In your example, Chunky, there is a lot of bolognium, but much of it is, as someone suggested before, essential to the story line, ie: dilithium, warp plasma, temporal node, Data and his emotion chip. Given those things, their actions are expected. That they waste time taking a turbolift (which, have you noticed, always go up and down, like elevators, even though the Enterprise is for the most part, a horizontally oriented vessel?), is for whatever dramatic effect can be accomplished in a 45-minute-long show.
