Seriously?
In the middle of a global crisis, this store asks you this. Really? Is it because they don’t match your outfit? Do you just like to live dangerously? It is for our safety though, right? You know how those masks can cause you to spread germs. Why would you want to take a chance and cover your face with such a thing?
It is better to stay uncovered so that nothing will get between you and whatever wonderful things are in the air all around you. You should also lick random things. I hear that keeps you from getting sick as well. Washing your hands is another risky thing to do so you may want to avoid that.
