Being Dominant doesn't preclude one from also behaving as a Gentleman.  There is no excuse for being impolite or rude to others.  Being a Dominant has nothing in common with being domineering, in fact one is a contradiction of the other.

A Dominant does not posses an unbridled supremacy or limitless power.  The Dominant posses only the power in which his submissive has granted to him.  It is the responsibility of a Dominant to ensure the submissive knows what the submissive's rights are.

It is the responsibility of a Dominant to teach the submissive information about the Lifestyle.  To insure the submissive grows and develops under the Dominant's ownership, in both the lifestyle and the public life.
