Many people are not used to ordering food with their mobile phones. When the high-speed train attendants push the dining car out for sale, they can buy it directly on the spot. Or find the car where the high-speed rail dining car is located and buy food on the car, which is also a good choice.
In addition, some people now put some bread, biscuits or instant noodles in their bags when they go out. When you take them out for dinner, you don't have to buy food on the high-speed rail. After all, the food on the high-speed rail is more expensive.
