Teacup formality is a part of etiquette, but an infinitesimal part. How about fast-food informality? That is as much a part of etiquette as the teacup. It is all of our behavior and not simply the formal occasion behavior. And, in fact, the more informal the circumstances, usually the more you need etiquette.

Judith Martin (b. 1938) American author, journalist, etiquette expert [a.k.a. Miss Manners]
