Does the dishwasher only go to work during meals?

Dishwashers don't just go to work while eating. Dishwashers are service personnel employed in restaurants, hotels and other places, responsible for cleaning and disinfecting tableware and kitchen utensils. Their working hours are flexible and need to be adjusted according to the business hours of restaurants or hotels, including breakfast, lunch and dinner. Therefore, dishwashers not only go to work during meals, but also need to work during the whole business hours.
