The Facebook page 'Retail Life During COVID-19' has attracted tens of thousands of followers.
According to Newser, it was started by retail worker Samantha Clarke, who works at a store in Modesto, California.
Customers aren't allowed to enter without wearing a mask and following other novel coronavirus-related rules.
Clarke was used to being insulted and threatened over the policy, but she never expected to be punched in the face and knocked to the floor.
