KFC's door-to-door delivery must be signed by customers, because it is a standard system of their company and a kind of affirmation and recognition for consumers. Their people will confirm your order to ensure that you will not miss the product, or take less or take the wrong one, so that you can eat with peace of mind. KFC door-to-door delivery does not pay directly. When you place an order, Alipay and Tenpay will pay.
