Can you rate KFC without popping up a review?

Yes.

KFC will pop up a review after placing an order, but if the user does not want to fill in the review, they can also choose not to fill it in. Users can skip the evaluation step directly without affecting the purchasing experience. KFC respects users' choices and will not force you to fill in a review. The purpose of this design is to give users more freedom and convenience, so that they can enjoy food more easily.
