They can’t require you to wear a mask if you have a “medical condition” that puts you at risk(interpretation held loosely by my medical professional called me). And they are not allowed to ask you about it because of HIPPA laws and privacy. I told them that at Costco on Friday and they didn’t even batt an eye. They just got another “complementary” mask for the person behind us that didn’t have one with them.  It was so satisfying...
