In the short story, "Just Lather, That's All," Captain Torres goes into the barbershop to see if the barber will attempt to kill him. The barber is a rebel, and the Captain has just returned from an expedition searching for the rebel troops.
The barber faces a moral and cultural dilemma; he has the Captain, literally, at his mercy as he could kill him in an instant with his razor. As he shaves the Captain, he ponders that he is "a revolutionary, and not a murderer." The barber does not kill the Captain; instead, he simply gives him a shave. The barber's morality wins as he thinks, "You are an executioner and I am only a barber."
On the other hand, the Captain walks into the shop and asks for a shave. He does not let on throughout the process that he knows the barber is his enemy and could easily kill him. He shows no fear. The Captain acts out of machismo and is willing to risk his life to see if the warning was true that the barber would, indeed, kill him. He tells the barber at the end of the story that he went in for the shave to confirm the rumor but " . . . killing isn't easy. You can take my word for it."
