One is that customers complain that you delivered meals in advance and didn't receive them. The way to avoid it is to send it to customers and reorder it. I really can't contact the customer. While the report could not contact the customer, the APP sent a message to take a photo and leave a message. The order has been delivered.

The other is system grabbing. For example, if you deliver the goods at a point 500 meters away from the customer, and then pass the address of the customer's location within 30 minutes, it will be judged as early delivery.

Another is that the rider doesn't order or forgets to order, then delivers, and then leaves the customer orientation to order and deliver together.
