It is not hard, but that is not the point. If the point is to protect yourself and others, why are you not wearing it all the time? Why wear it only for being seated and leaving? Why not wear it while you are sitting, conversing, ordering, waiting for your food, eating, waiting for the check, and paying? Can the virus only travel at a certain height from the ground?
I would like an answer to each of these questions, my good sir.
