The above sign, without the mask requirement, is commonly found posted at the entrance to many business establishments in the US and has been so for a long time. As far as I am aware, it has not caused any controversy and shirtless or shoeless people have not threatened the businesses with lawsuits. And yet, because mask wearing has been made into a culture war issue by Donald Trump, we now have the bizarre spectacle of people doing just that. Take this case:
Hugo’s Tacos, a beloved LA chain, announced Sunday that it was temporarily closing both its taco stands after its employees reported increasing harassment from customers who refused to wear masks during the ongoing coronavirus pandemic.
The harassment – ranging from racial slurs to food and objects being thrown at employees – “has taken a toll” on staff, CEO and part-owner Bill Kohne told BuzzFeed News. Kohne said he wants to give his employees a break as the company works toward solutions to better protect them.
