The concept of Internet of Things, which appeared in Wuxi Exhibition, can reduce the queuing time. Very clever, if you choose a dish in a designated place, the price of the dish will be automatically calculated. You have to ensure that the price tag is online, and everyone is within 4 seconds, and no one is watching it. If it is a line in the traditional window, it is normal for everyone to spend a few seconds.

When it comes to the canteen, I believe most people will sigh first. Their idea must be to queue up desperately. But in recent years, with the development of science and technology, the canteen has its own black technology, which perfectly solves the disadvantages of traditional dining in the canteen and creates a new word "eat and eat".

It's simple. Your situation is similar to my high school. See if anyone in the queue knows you. If so, have him call you. Even if someone asks and wants to say something, just tell them that you asked him to help you line up. This is how I spent most of my three years in high school, because our class is on the fifth floor. Hahahaha ... but it's really a way to buy. There are still 1-2 minutes before class is over. Let's go and cook. There is such a student in our class. He has run downstairs before class is over. When class was over, he had already run to the canteen. When the teacher found out, he said to go to the toilet. Ha ha ha ha.
