Service Brat

A service brat is a brat who enjoys being of service.

Whether they helpfully scale back the brattiness so that some service actually gets done, or they simply cannot help being sarcastic or fidgety while they kneel in service, it's the contradictions of life that these folks enjoy.

Imagine a sassy piece of human furniture that can't stop cracking jokes, and doesn't mind a spank or a little spilled drink for their trouble, and you probably aren't far off.
