We can't really define the different stages of this story – Hemingway defies many of the conventions of the short story genre here, including the whole "story" part. "A Clean, Well-Lighted Place" is more like a character sketch than a plot-driven piece of fiction; this lack of plot draws our attention to the main theme of the story: life, both in literature and out, can be seen simply as "nada y pues nada y pues nada" – nothing and nothing and nothing.
