It’s all honor system
which is 100% not going to work. if you're anti-vax, but your lack of vax is preventing you from getting your mitts on trader joe's deals on cheese, how long do you think you'll spend on the moral dilemma before boldly declaring you've been jabbed? i'm thinking less than planck time.
so the question, for me, becomes: there are going to be unvaxxed and unmasked people around me - how comfortable am i with that? i'm OK for my own sake, but i do worry about the kiddoes.
