Most people dont wear masks properly to begin with, and when they do they are constantly touching it and spreading their crap everywhere so a lot of the mask wearing actually is worthless.
I travel MO and KS working in a different hospitals and every one has their own standards and what not, they are just running off the cuff of what they think is right.. I love if they ask if ive traveled out of the county. I say yes and they let me in, they ask if i have symptoms and i say, well i coughed and had a sneeze today, they still let me in...... they use worthless forehead info red thermometers that read wrong every time. Hell today the thermo read to low to pick up anything so they let me in anyways.
