So, my office building has decided to reimpose a "mask" requirement to enter/leave the building, and in all the public places within the building.
The requirement is to wear a mask or a "cloth covering" over the face. My scarf, which looks more or less like the one in the picture below, counts:

How ridiculous is that? It's a chunky knit with spacing that a small fly could fit through, but it passes as a valid "cloth covering" as long as I have it wrapped around my face when I enter the building.
