Yeah I wouldn't care for my fries to be cooked overlong and near burnt, but I do like them to be cooked for their proper time (usually about 2 and a half minutes). Fast food places are often guilty of "pulling" fries and other foods early from the deep fryer in order to serve the customer faster. I'm not sure that's too healthy so if I ever go to a ff restaurant when they are slow or dead, I tell them I am in no hurry and to please let the fries cook the normal time.
