A common form of television commercial. Alice and her less attractive friend Edith are discussing a domestic issue in the kitchen, with The Product being the solution. Coffee or tea is often being sipped. Generally, Alice is the one to help out Edith by suggesting The Product. The trope is still in use, but not as prevalent as once it was. Often abbreviated "Two Cs in a K" or even "2CK", the trope name is the politically correct version of the industry term for this set-up, which does not use the word "chick," but...a different C-word. (And you thought Mad Men represented marketing's past.)
