Wrong. There will be at least one store for each of your needs that will allow you to be maskless. Use the medical condition excuse, if that doesn’t work, go to a place with a self checkout and use that, ignore anyone who tries to talk to you. I have found many more stores then I would’ve thought simply don’t care enough, and others that silently refuse to enforce. If I walk in and the guy behind the counter or an employee has his mask down, I’m not wearing one, I don’t even need to use the medical condition. Don’t give up so easily
