I've worked in a McDonalds. My experience is outdated by a few years, but I don't think I ever once saw real food prep happening in store. Every ingredient is processed at the factory, sealed up and shipped to the store with timestamps and dates for when it expires and should no longer be used. Even the cookies arrive partially baked, with the store doing a minimal final round of heating, all for efficiency. The store workers are basically just doing final assembly for the vast majority of products, and the fries are certainly no exception.
