Tired. The old uncle's dishwasher is tired, and washing dishes is a very tiring job. Dishwashers need to handle a large number of dishes in small restaurants or medium-sized or large restaurants, which need to be completed in a limited time. This requires keeping a bent posture and repeating the same action. This kind of work is prone to fatigue and low back pain. In addition, if the restaurant is large, dishwashers need to stand for a long time, which will also increase fatigue and discomfort. Generally speaking, the dishwasher has a heavy workload and needs to pay a lot of physical strength and energy.
