I would say choose your places visited as well as you can. When I was on social media we had a group dedicated to businesses that were mask less friendly to shoppers for example. Now more and more people are showing up mask less in places around me. If those type places can’t be avoided we’ll be aware and safe. The old saying is “you can’t fix stupid”, well stupid and scared sadly is even more dangerous so always be aware of your surroundings. If confronted simply and calmly respond no thank you, if you must leave leave... Control the situation with a level head and kindness in how to respond. Be safe :)
