John Steinbeck explores many themes in "The Grapes of Wrath"; such as, the importance of avoiding stereotypes/labels and the need to share what we have with others. Steinbeck conveys these two themes through setting and characterization.

When a poor man enters Mae's hamburger stand, she was very reluctant to sell him a loaf of bread. After Al growls at Mae, she obediently sells the man bread...
