In John Scalzi's book "The Dispatcher," a humorous exchange highlights the concept of "resting smug face," suggesting that some people naturally carry an expression of smugness even when they do not intend to. This playful banter between characters points to how perceptions can differ from intent, making for a lighthearted moment in the narrative.

The dialogue emphasizes the idea that facial expressions can sometimes convey emotions or attitudes that the person may not be aware of. This serves as a comedic reflection on self-awareness and the judgments people make based on appearances, adding depth and humor to the characters in the story.
