People have forgotten the skill of walking away from out of control crazies.
However having clerked in retail the clerks have a certain degree of control over those heated customers....walk away from the counter and get management to handle it. That goes with the job.
That is because it doesn’t work any more. Crazy just attacks you when you turn your back.

Yup, that why the powers that be get paid the big bucks. They can also call security or cops, if needed, to take care of a crazy.
