In the application Meituan, users can see the real-time position of the delivery worker and know the relative distance between the delivery worker and the user.
Once I had two orders, one of which was further but more urgent, so I decided to deliver it first. On the way, I got a call from the person who had placed the other order, asking why I rode past the residential quarter he lived in but did not deliver the food to him.
