In literature, the word "clientele" is often imbued with nuances of exclusivity and sophistication, suggesting not merely a group of customers but a distinct set of individuals characterized by refined taste. For example, in Emily Post's "Etiquette" [1], the term is employed to describe the young and smart patrons of a Parisian jeweler who have contributed to the brand's vogue in New York, thereby linking the concept of clientele to both cultural influence and social prestige.
