What you wrote in your health policy: “masks are encouraged but not required”
What I read: “Anti-maskers are welcome here. We wish the more vulnerable members of our community would just die and stop inconveniencing us.”
@mossmann "Masks are encouraged but not required"
No, they are not encouraged or you wouldn't phrase it that way.
"Please wear a mask" is how you express encouragement. You don't have to say "not required". Saying "not required" except when explicitly asked is saying "masks are DISCOURAGED".
