I just overhead one cashier say to the other "We're going back to masks tomorrow". I don't know if it's just for the employee's or everyone, but given how corporations are in lockstep with the CDC I'm going to guess everyone.
I'm not doing it. If someone tells me to where a mask I will tell them to call the police and have me arrested for trespassing and continue shopping. The flash mobs of maskless shopping protestors needs to become legion. If they won't ring us up fill up the carts and abandon them.
