Yeah, no, that is a really bad idea. Store employees should not be approaching people who are by law legally not wearing a mask. It is asking for a dangerous confrontation, which cna, and already has, become deadly. If a store hires a security company or police officers, those people could reasonably enforce a mask requirement, but that's the key..."requirement". Until it is law that you wear a mask somewhere, you should understand that your beliefs are nothing but an opinion formed on sketchy-at-best information/data.
The idea of having store employees escorting customers out of a store for not wearing a mask is incredibly dumb.
