School catering has always been a business to ensure the harvest in drought and flood, and has a stable source of tourists. In addition, the control is very strict now, and restaurants around the school that do not meet the license requirements are closed. Moreover, school catering is subsidized and the price has a competitive advantage. These are the advantages of school catering.
But dry catering needs to be prepared for hardship in advance. Dining hard, busy getting up early and getting greedy every day. There are still many trivial chores for you to deal with.
I summed up the secret of successful catering: delicious, moderate in price, smiling, hygienic and clean.
