The three jobs about which I am curious

1. Being one of the pair of workers who, in our home town of Moora WA, who had the job of collecting full sanitary pans from toilets, replacing them with empty pans and emptying the full pans into an out-of-town deep hole. They worked Monday to Friday and wore thick leather aprons and water boots as protective clothing.
2. Being a person employed for a minimal wage to identify and remove noxious weeds and thistles grieing amonst the acres of wheat that have been planted on a farming property.
3. A person employed to clean out accumulated droppings from all the fowlhouses in the district, bagging the volume of waste and taking it to my boss who sells it to gardeners and green thumbs in the marketplace.
