no. In the catering industry, the opening time usually refers to the time when the restaurant staff arranges seats and orders for the customers after they enter the restaurant. The ordering time refers to the time when the customer submits the order to the waiter or cashier, usually after the opening of the table, and after a certain period of time, the customer orders. Order time is usually used to determine the meal time, so that the chef department can allocate the meal time, ensure that the dishes are processed within a reasonable time, and thus improve customer satisfaction, so the opening time is not the order time.
