When the rollers hit the expansion joint, the sheet wiggled. I continued on to the vending machines, stared at them for a few moments, and just went back to work. Nosocomial diseases are diseases spread through hospitals themselves, from patient to patient. Hospitals are dangerous places. People die there.
People go in with one thing and die of another.
Hospital workers have increased risks of just about everything that can be caught. They hired another guy, and apparently some of the other people didn't like him, but I told our boss he was a good worker. He explained to me one night, that the hose attached to the faucet in the janitor's closet was illegal and dangerous. If water gets left in the sink, the hose could suck up dirty fluids into the clean water system if pressure changes occur when the tap is open. And once in the system, they can be devastating, and very hard to clean out.
