@maisondagoitpublications Mildred Pierce, by James M. Cain and The USA Trilogy, by John Dos Passos, Mad Men Season 7, Episode 8 ("Severance"). Roger said "Hey Mildred Pierce. Can I get the check?" referencing the novel by Cain. The waitress was reading the USA Trilogy. Mildred Pierce was a middle-class housewife who separated from her unemployed husband and supported herself and her children as a waitress.
