Nope, I will go in without a mask, if someone says something, I will turn around a leave, letting them know it is because they are requiring masks.
Simply not going doesn't inform the business as to why they are loosing customers and is pointless.
Although, it should be note I am not antimask, I am antimandates. For example, I don't think that anywhere should be allowed to require proof of vaccination for employment or for their customers, just as nowhere should be allowed to say you have to wear a mask. They can encourage, sure,maybe even offer a discount to those that do, but not refuse service to those that don't.
