Rummy Mitchens: She is an example of the failure of the Salvation Army and what was known as `souperism` – using food to bribe people to convert to evangelical religion. Although she takes the food she needs and pretends to the beliefs (and fakes sins) to make the Salvation Army staff happy, she does this only for the sake of food.
Snobby Price: Like Rummy, he is also in the play to show the failure of the Salvation Army. Although he pretends to piety, we can see that it is faked simply in order to get food, and in fact, that all the Salvation Army has done is to make a hypocrite of him.
Lady Britomart Undershaft: In some ways she is simply a comic foil, of conventional respectability, but on the other hand, one can see in her a sort of strength that matches that of Undershaft and produces Barbara.
