The number of dishes and utensils a dishwasher will wash on a busy night in a large restaurant can vary widely depending on the size of the restaurant, its menu offerings, the number of customers served, and the efficiency of the restaurant's operations. However, I can give you a general estimation based on common scenarios.
In a large restaurant, especially during peak hours, it's not uncommon for the dishwasher to handle hundreds to even over a thousand dishes and utensils in a single night. This can include plates, bowls, glasses, cups, silverware (forks, knives, spoons), pots, pans, and various kitchen tools.
On extremely busy nights, such as holidays or special events, the number of dishes and utensils can significantly increase. Dishwashers in busy restaurants often work quickly and efficiently to keep up with the constant flow of dirty items from the dining area and the kitchen.
It's important to note that these numbers are just estimates, and the actual count can vary depending on the restaurant's specific circumstances. Large restaurants with a high volume of customers and extensive menu options will naturally produce more dishes and utensils, requiring the dishwasher to work diligently to maintain a clean and orderly kitchen.
