Who is The Woman at the Automat from In God We Trust, All Others Pay Cash and what is their importance?

The elderly woman at the Automat is unnamed. She appears in "Duel in the Snow, or Red Ryder Nails the Cleveland Street Kid." She eats lunch at Ralph's table at the H & H, and gives him a pamphlet detailing her opposition to war-type children's clothing and toys. She is also a vegetarian, as she believes that meat-eaters are doing the work of the Devil. She wears a button that reads, "Disarm the Toy Industry."
