Dishwashers usually need to stand by the sink for a long time, constantly cleaning and wiping tableware, pots and pans and other kitchen utensils. This work requires meticulous patience, usually in a busy restaurant environment, so it may be necessary to handle a large number of tableware quickly. Dishwashers also need to deal with food residues and detergents, and may come into contact with some chemicals, so it is necessary to pay attention to safety and hygiene.

Waiters need to keep walking around the restaurant to provide services for the guests. They need to remember menus and special requirements, send orders to the kitchen in time, and send food and drinks to the guests' tables. Waiters also need to communicate with guests, answer questions, handle complaints and maintain a polite and friendly attitude. During peak hours, waiters may need to respond quickly to the needs of multiple tables while maintaining efficiency and accuracy.

Generally speaking, dishwashers and waiters are jobs that require physical and psychological efforts. Dishwashers may need to stand and carry heavy objects for a long time, while waiters need to walk around and interact with guests frequently.
