The average person's understanding of the heavy use of prepared dishes in restaurants may vary depending on personal experience and opinion. The following are some common views and understandings:

1. Convenience and efficiency: Some people believe that the use of prepared dishes in restaurants increases efficiency and speed of service. Pre-prepared dishes are often processed and prepared in advance, reducing the amount of time it takes to cook them on-site and allowing restaurants to serve food to guests faster.

2. Consistency and standardization: Prepared dishes are usually made according to standardized recipes and production methods, which ensures consistency and quality stability. For chain restaurants or outlets, this standardization ensures that the taste and quality of the dishes remain consistent across different locations.

3. Ingredient supply and cost control: Prepared dishes can be prepared and processed in advance, allowing restaurants to better control the procurement and inventory of ingredients. Additionally, there may be cost efficiencies associated with large-scale sourcing and production of prepared dishes, reducing labor and time costs.

However, there are some people who may hold some skeptical or questionable views about the mass use of prepared dishes in restaurants:

1. Quality and freshness: Some people believe that prepared dishes may not be as fresh and of superior quality as those cooked on-site. They may be more inclined to enjoy dishes cooked on-site, believing that it is better to ensure the freshness and taste of the ingredients.

2. Health and Nutrition: Some people are concerned that prepared dishes may contain additives, preservatives or other unhealthy ingredients. They may prefer using fresh ingredients and cooking on-site to ensure the nutritional value and healthiness of the dish.

3. Personalization and innovation: For some, live cooking represents the chef's individual creations and the uniqueness of the dish. They may prefer to enjoy a unique dish experience at a restaurant rather than eating standardized dishes that make heavy use of pre-made dishes.

It's important to note that the use of pre-made dishes in restaurants has to do with practicality. Some restaurants may use pre-made dishes to increase efficiency and control costs, while others may focus more on live cooking and personalization of dishes.
