The story’s simplicity
and thematic austerity has many critics ridiculing Hemingway while his admirers contend
that ‘‘A Clean, Well-Lighted Place’’ is Hemingway at his most pure
as

he captures
in both form and content an irreducible and tragic essence of
life. 

The older waiter
sympathies that lie with the old man point to the existential condition of man whose
life is simplified to "nada" and he must struggle to find some light in the darkness of
nothingness.  He does this by finding a place that is clean and well-lighted where he
can be with others in and where he can display good form and conduct.  The old man
displays good conduct as he sits in the cafe and "drinks without
spilling."
