There’s also the root problem of employees having no agency to kick out misbehaving people. There’s this whole “the customer is king” ethos in American commerce and this is enabling the worst people to harass people without any consequences. If you are getting kicked out and banned from most stores in your town because you are an abusive asshole, you might think again about your behavior and maybe even change. If everything that is coming from your bad behavior is that some random employee is getting fired, yes, this will enable even worse behaviour.
