Why do you use trays for catering?

It is not only convenient, but also can prevent tableware and food from being polluted and keep clean and hygienic.

The main function of the tray is a tool for transporting dishes. Generally in hotels, the tray is lifted horizontally with the right hand. Put five bottles of beer on it (the beer bottles are full of water) as long as the water doesn't overflow. If it is a hot pot restaurant, most of them are raised directly above their heads.
