"If there is one thing that a really well-bred individual cannot overlook, it is cheapness of behavior. Cheapness of behavior has nothing whatever to do with lack of money. The great heiress can be cheaper than cheap - and the poorest girl in town a complete thoroughbred. But no one can be both cheap and a thoroughbred.

The typical meaning of the word "cheapness" is exemplified in the girl or woman who puts no value on herself; who shows no reserve mentally, morally, or physically; who confides most personal and intimate details of her life to strangers; who, exacting no courtesy, does not mind being nudged or pushed or shoved; and, having no sense of personal value, is willing to be kissed, and petted - in other words, to put herself in a class with the food on a free-lunch counter." - Etiquette, Emily Post, 1945
