There are many couriers in the same city. For example, SF Express, Meituan and Hungry all provide the same city express service. It doesn't necessarily matter which is faster. Generally, riders run by the order, so as long as your city is not very big and the system scheduling is not outrageous, it can be delivered to you within the time planned by the big data system. As for the injury, it is even more difficult to say. You can remind people to be careful when taking orders, and people will usually pay attention. Besides, if the food delivered now is damaged, it is generally possible to claim compensation. I hope it helps you.
