Sales must be in the best situation, and the performance of the best window is like this.

But many windows are unlucky, because no one goes to the location, taste and price.

According to the average 10 yuan for a meal, 4,000 yuan is 400 meals, and on average, more than 100 meals are sold. I don't think there will be more than 100 people waiting in line at a window for an hour. Zhengzhou University, with the largest population, is not so exaggerated.

If the price rises, the number of people will inevitably decrease, and there may not even be a door.

The window position where people ask for money or the business of selling rice before must be poor.
