Take a look at this story, where covid-positive hairdressers interacted with over a hundred clients (all involved wearing masks) without infecting any of them: https://www.cdc.gov/mmwr/volumes/69/wr/mm6928e2.htm https://www.cdc.gov/mmwr/volumes/69/wr/mm6928e2.htm Masks are tremendously effective. They protect you from others a small amount, but protect others from you a huge amount. They are absolutely not theatrical. When it comes to stopping transmission, we don't have to get 100% effectiveness. We just need to get the r-value below 1 and the disease will die out. It's a game if probabilities, not absolutes. Masks have a very low cost for the tremendous benefit they confer.
