Well, I meant face coverings in general as a defense mechanism against viral spread, but yes even different levels of effectiveness among them - again with the exception of the N95's. The ones you mention are typically single layer, which is the least effective. But in reality, all of the cloth coverings become germ farms because people are constantly pulling them up and down and not washing them after each use.

Back on topic, I saw the post about server shortage at an Olive Garden. For all the discussion here, I haven't personally experienced it, only heard stories. We're only going to restaurants about once a week these days though.
