You the property owner can turn off your radio, sure, but what if the radio is broadcasting fart sounds? You wouldn't want to have the reputation of the business where customers could turn on their radio to hear fart sounds, would you? Or embarrassing facts about you or your business, maybe. Or worse. Hitler speeches?

If they have to opt to turn on their radio, and tune to a frequency, how is that substantially different from just using their cell phone to read bad reviews about your business? Besides, jamming radio signals off of your own property is illegal, so this is only really relevant for ham bands.
