This is evident from the following details:
* Setting: The story mentions the protagonist, George, living in an "apartment house on the Grand Concourse" and working at a "store on 161st Street," both of which are prominent locations in the Bronx.
* Atmosphere: The story captures the gritty, working-class environment of the Bronx in the mid-20th century.
* Characters: George's neighbors and colleagues are described as typical residents of a working-class area in New York City.
While the story doesn't explicitly state the exact neighborhood, these details strongly suggest the setting is in the Bronx.
