I’ve noticed at restaurants, waitresses are always touching their faces and adjusting thier masks...
even assuming the mask worked.. if you take it off the wrong way (touching the outside of it in the process) ... all you did was concentrate the virus in one spot and transferred it to your hands, which you will then touch your face with before long.
I haven’t seen a single person remove a mask properly to not get infected from the mask itself, or wash hands afterwards if they did.
everyone does it, no one has been trained on how to properly take them off.
