When I lived in Western Kansas there was a rendering plant outside town. When you passed and the wind was blowing the wrong way you simply tried to hold your breath until you passed the place. I could not imagine having to work there.
I also saw an interview on TV of a woman who worked cleaning the large public toilets in India. She hated the job but could not get anything else as she was an untouchable. I really felt sorry for her.

There was one of those near here many years ago. At night it would stink up the whole county. One night it burned down. No problems since.
Some years ago a friend of mine, a delivery truck driver, had to make a run to one outside of Mendota, Illinois. He said the smell inside was so awful he dropped to his knees with the dry heaves within a few feet of stepping through the door. When he got back to his terminal, his boss took one whiff of him and sent him home early. He had to leave his clothes outside for several days before they were “presentable” enough to throw in the washer.
