Lol what? The point is that you reduce the spread of germs from coughing and breathing as well as taking them in by breathing in germs. Gloves and a suit would of course be even better but nobody is going to expect the average person to go to such lengths. It’s far more reasonable to ask someone to just wear a mask. Only an idiot would believe a mask would filter the virus but it certainly limits the spread of germs. Would you rather someone sneeze in your face with a mask on or off?
