The mail carrier that came to the building today was VERY "off." He said his name was John. He had half a mask on and no gloves. But most suspiciously he had a horrible cough and was shaking. Again, half the mask was off of his face. I asked him if he was OK and he said that he was "very hot." He needs medical attention. I tried calling the P.O. but as usual could not get through to anyone. Mind you, this gloveless mail carrier coughed while delivering mail and scanning packages (which he left scattered ALL over the place). I can not believe that any Supervisor would allow this person to work. Lastly, there has been an entire crate of mail resident left here in the building going on over 48 hours.
