With incredibly stupid people in this nation who do not understand how simply wearing a mask can improve our odds of overcoming a deadly pandemic, I am pleased and heartened to see that Costco has ramped up their mask policy requiring those with medical conditions to at least wear a face shield. With an ignorant sister in law who believes the pandemic is a political "hoax" I am sure intelligence-challenged people like her will avoid Costco. But luckily for the rest of us, these people never shop at Costco (their loss) anyway!
