What evidence in "Just Lather, That's All" shows that the author knew enough about barbering to establish the professionalism of the barber?
In the short story "Just Lather, That's All," the barber engages in acts common to a barber. The author demonstrates evidence of knowledge about the profession of a barber early in the story. He opens the story by discussing how the barber is moving his blades back and forth over a strope. A strope is used to sharpen the blades making the cutting more specific. He also indicates that a blade is held up to the light to ensure its sharpness and that it is tested on the barber's thumb.
As the author glides the reader through the story he details the barber's actions such as slicing off pieces of soap which are put into a cup and swirled around to make a rich lather. He even demonstrates that a barber would assess the amount of days of beard growth a customer would have. In addition, as the barber begins to shave the man he does so in a specific pattern by beginning with the sideburns and moving downward. The barber also continues to keep his blade sharpened as he shaves the man, and he wipes the soap away routinely in order to reveal the areas so as to be able to determine if he has missed a step.
