It would be nice if the restaurant owner could use the time slots for his orders, so as to improve management.
For example, it would be nice to let the customer choose what time to receive the order, while for the restaurant to put a limit on orders per hour, for example from 10:00 to 11:00 the restaurant can only make 10 deliveries, while from 12: 00 to 13:00 20 deliveries (it would be nice to decide with times of 30 min)
