He didn't claim any exemption which is one problem with that argument. The store is under a mask mandate order, doesn't matter what the person walking in feels about the mask the owner has a right to order him out of the store given that not doing so could result in him being shut down. I disagree they had any right what so ever to even touch the man, that should have been left up to the cops period....but they do have a right to protect that which will get taken from them by not requiring those entering the store to mask up.
