KFC's door-to-door delivery is free of charge. Business circle, 30 minutes, 40 minutes. If it takes more than 5~ 10 minutes in the business circle, it can be delivered. If it is too far away, first, the food quality cannot be guaranteed, and second, it cannot arrive within the specified time. If you insist on ordering takeout in a place too far away, you have to pay for taking a taxi back and forth, and the shelf life of French fries is short.
