you're an idiot. What gives you the right to decide how someone should act. Some people, especially from asian countries, have been wearing masks during flu season in this country for decades. Did you say "oh, don't do that, it doesn't work then"? If someone feels a mask makes the feel safer, that is their right, just like if a provider doesn't want to go down on you or rim you if you haven't taken a shower. Oh, and let's get to the ineffective part...... why do DOCTORS wear masks during surgery? If masks were ineffective they would not be doing that. Stop judging people how they act and worry about you. And if you won't see a provider with a mask, all the better, because they don't want to see you. Oh, and one more thing, some providers look better WITH a mask on.
