"I said I quit." (24)
By quitting, Sammy is attempting to defend the girls' principles and define his own. His act requires courage and daring.
"You didn't have to embarrass them."
"It was they who were embarrassing us." (26-27)
This exchange between Sammy and Lengel shows their conflicting principles. Lengel sees the girls as being disrespectful and thinks they are purposely violating the established order just to make mischief. Sammy, however, doesn't think it's right to behave rudely.
