The complexity of a D/s relationship is limitless and never textbook, what one Dom would consider very disrespectful and none submissive behaviour another would laugh and just consider it cheekiness.
My personal relationship with my Dom is very relaxed and playful, he fully admits he enjoys my bratiness. We laugh together a lot, I'm not shy to voice my opinion or challenge his authority at all it usually followed by some sarcastic comment as soon as he's asked me to do something.
My favourite is to ask him to "say please" to me when he tells me to do something which is usually met with "get on with it!" In a sharper tone, i usually fall back with laughter because I never get tired of my Sirs face!
Some brats seek physical punishment as a reward for their bratty behaviour, that smile on the old man's face does me just fine! :)
