A Mask-less Shopper walks into a Sprouts Farmers Store filled with Euthanasia Volunteers

If they mask holes refuse payment. They debt is discharged and considered to be paid under commercial law. If they won't accept your payment in the current currency used for payment (Federal Reserve Notes) take your shit and go. You are not shoplifting as they refused to accept your payment.

They are also violating the ADA. You don't accept wearing a mask, and you agree not to sue them for trying to make you wear a mask. You have a contract that will hold up. If they continue to break the contract sue them.
