As for the rent of 1800, I don't think everyone should be too angry, especially outsiders. We have relatives selling vegetables (suburban vegetable markets), and the rent is more than 800 yuan in January, but they are tired, and they still earn hundreds of thousands of dollars every morning.
Different places, different geographical locations, and even different ports in the same vegetable market have different rents and admission fees (your so-called sponsorship fees and food and drink fees). If the stalls in the vegetable market can't be rented out, he will naturally reduce the fees; On the other hand, if the market management office is in short supply and is not in a hurry to make up the house, it is normal to charge a high admission fee. There is no law that people can't charge like this. They are all willing to fight and suffer.
