‘I’m Not Asking You, I’m Telling You’: LA Mayor Says Customers Without Face Covering Must Be Denied Service I have a medical condition and the airline required me to wear a clear splash shield instead of a mask as the minimum requirement to board the aircraft. Which I wore like a hat. I was the only person on the plane not wearing a mask because they literally threatened to throw other people off the plane for not wearing theirs properly for the entire flight. They kept coming around checking and making people fix their masks if not being worn properly.
