How does The Biedermeier's continental breakfast represent a sense of security for the residents in the novel, Women’s Hotel?

When Mrs. Mossler can afford to serve the meal, the Biedermeier girls feel comfortable and at ease. When she can no longer afford to serve the meal, the residents experience a sense of scarcity. Without this included meal, they must either go without food, spend money they do not have, or steal food and money from others.
