It's a large part of why walk-up RP can be so bland at times. You're trying not to step on any oversensitive toes, and nobody wants to play the submissive/servile Imperial (which is what most ought to be).
It doesn't have to be submissive or servile, just respectful
of their title, position, and power. The problem is that for many people showing respect is the same as being submissive, because they're RPing for a power fantasy.
And similarly, a Sith can be respectful of the abilities
of others without lowering themselves. Sith aren't independent monomaniacs, they are at the top of a society. For that society to function, there has to be an awareness of the value Imperial agents and Bounty Hunters and others offer, and while their position may be superior, they shouldn't just be instantly abusive to everyone.
