if a person had a right to be served, then you can thru the power of a right compel/force someone to do something for you, and that's unconstitutional.
no citizen has the power over another citizen to force him to do anything, against his will.
where does it say you have to be treated equally, in the sense that i must serve you, ....if i create a transaction with you, then i must treat you fairly under the law, however i dont have to create such a transaction.
what you saying is becuase you dont like the way some people behave towards other people in an unkindly fashion, then those people thru the power of force by government ......should be made to serve others against their will.
this is not logical becuase the foundering fathers did not give the federal government power over the people to do such a thing...in fact no power at all.
