Excuse me, what is the job of the kitchen stall?

It's not work. OpenKitchen is a popular way of eating in the catering industry.

Open kitchen usually refers to a transparent glass partition between the dining area and the background, through which guests can see the whole kitchen and its operation process. Doing so is conducive to improving food safety and hygiene standards, and can increase customers' trust in the cooking process and quality of dishes. It can make customers better understand the information such as the cooking process and the source of ingredients.
