If you are were a mask while not sick, you are delusional. It is hygiene theater. Unless it is a properly fitted N95 mask you are doing nothing than giving yourself false security. Having a venue specifically for the immuno-compromised is fine and all but if there are not enough of them to keep the business afloat, boycotting them wont change that. Maybe having specific events hosted at the bar would work better than expecting everyone at all times to cater to a specific demographic. Also the sorts of people that dont wash their hands and cover their mouths with their elbows while coughing dont care and infact actively try to negate the efforts of others.
