Years ago i worked for the county Parks and Recreation Dept. where i lived.Cleaning the public bathrooms was...unpleasant.We finally rigged a pressure washer on a trailer.You would pull up,put on a full length rain coat,rubber boots,hat and goggles and blast away.
Then there was pest control.I would walk in houses where the walls and ceiling were covered with roaches.Taking a can of 565,(think Raid on steroids)
i would begin the assault.Dead or dying roaches would fall on your head,down your shirt collar and into your pockets or crawl up your pants leg.I saw guys get back to the office after that,turn in their gear and walk out the door.
