They piss me off too. Plus those people look like morons. It must be a requirement, but some take theirs off, and most constantly fiddle with theirs -- up and down, on and off... In Lansing they were handing out masks saying you have to wear it to get through security where they would take our temperature off the wrist. I took a mask, and put it in my pocket where it stayed. The port-a-john was clogged with them! In my standing area, about 25% were wearing the mask, but maybe only 10% with any discipline or consistency.
