The automatic dining hall in china.(please to correct me if I am wrong THS) Today , I want to introduce our company of the automatic dining hall. In this place, there is no waiter for serving, you get your dinner by youself. It can save a lot of the cost of the canteen. But how it can run. Let me tell you. At first you need to use phone to sweep the two-dimentional code on the plate. There are much kinds of food on the table, about forty kinds. You need to put the tray on the fixed place so that the machine can distinguish the tray. Then you can use spoon the food to your tray. Because the money of food is counted by the weight. So there is a weight sensor under the food you want to get. The automatic machine can count the different weight bewteen before and after you get food to get know how much money you should pay. You can get any food and the suitable volume by yourself. About fifteen minutes( I think this time is enoungh for you to get what you want to eat.) the electronic bill will automaticly sent to your phone and the money will pay automaticly. After you finished the eating, you need to got to the plate recycling place to simply clear the bowl and tray you have used. At the all process, there is no waiter in the dining hall. It is our company's cateen. Do you like it?
