I was the only one wearing a mask.
That'd make me nervous, especially with heavier-than-normal breathing all over the place. Six feet distance isn't enough for sneezes and coughs -- it's been measured at over twice that distance. Plus it can linger in the air for a number of minutes, sometimes many minutes. Since cotton and surgical masks do very little to protect the wearer, I don't want to go near people who can't be bothered to help protect the people around them...! Stay safe, guys!
