1: generally contact the director of the catering department. Some schools are managed by logistics management departments or logistics groups. Basically, it is easier to go through the formalities before the winter and summer vacations in the school, because the return and entry are all handled and renovated during the holidays.

2. Every city is different. You can compare the charges horizontally.

It is generally impossible, unless you sell drinks and food at the door without affecting the overall planning of the canteen, which is estimated to be negotiable.

This contract is a standard contract. You basically have no room for negotiation. If there is, pay as little as possible the deposit, calculate as little as possible the rent in winter and summer vacations or not, discipline yourself less and discipline the school more.
