Thanks for this Dragon. I was kicked out of Costco today. I didn't really care, and didn't want to make too big of a scene, because my wife needed to get something for Thanksgiving (I try to discourage her from shopping there, even with a friend's membership card). I had a plan of attack, but they flummoxed me by offering a face shield instead of a mask. I suppose I could have objected to that due to religion, or not being sterile, or being cleaned with toxic chemicals, etc. But really, it was too stupid for me. How does a face shield stop viron from being exhaled, or inhaled? I could have taken it and put it on backwards, then make them show me wear directions for wearing it were in their policy.
