Anybody who actually feels that they have the "authority" to say something and that somebody else doesn't have said "authority" has reached the absolute peak of arrogance. Nobody has anymore "authority" or "credentials" to behave a certain way, or do certain things, than anybody else. It is something that is created by lazy people out of economic convenience to keep competitors from ruining their cushy business. What better way to run out competition then to have the government declare you are the only legitimate business allowed to operate?
