Is the dishwasher in the school canteen tired or the factory tired?

The factory is tired. Washing dishes is a tiring job. Generally speaking, a store starts to recruit dishwashers, which shows that the business of this store is good. If it is the catering industry, there are more dishes to wash and there is no rest time. It is generally not easy to get to the factory production line. Three shifts are better, about eight hours, and two shifts take longer. So the factory is tired.
