Rights are indeed commonly ranked. The civil rights laws represent a ranking of rights, as do a variety of land use and zoning laws, business licensing laws, etc. What right trumps what right, and to what extent, becomes a political and policy issue, subject to scrutiny by the courts. And the courts have, over the years, developed standards for deciding if the regulation or limitation of a constitutionally protected right has gone too far.
Personally, I think that a law requiring a business to let in lawfully armed customers would survive a court challenge. At least one federal court of appeals has upheld a state law requiring employers to let employees keep a gun locked in their cars parked on company property. But so far a law keeping businesses from tossing out legally armed customers hasn't been politically viable.
