I suppose if you want to take it to an extreme...then yes...but I would never frequent such an establishment...and think it would go out of business rather quickly...almost every state has a mask mandate for businesses with penalties associated with violating them...there have been some patriots like the gym owner in NY that said screw it and opened anyway and kudos to him...there are many businesses that do not have that bravery....or actually believe for some reason that the mandates are helping...no red pilling having happened yet...as far as what should be the line on what a business can or should require of customers I am not certain where that line should be...but I am certain going out and grabbing a gun and using said gun to get service is wrong...
