I'm glad my years working in retail were short-lived. Customers were often assholes 20 years ago, but the videos I see now are insane. The frequency with which customers seem to grab people, spit on them, or otherwise physically assault retail workers (and restaurant workers) just seems to be going through the roof. Serving someone who assaults an employee is completely insane.
I do think the timing of this walkout was dumb, though. Who was going to pay attention to a walkout on Christmas Eve?
