Clearly the proper procedure is to eat these fries first while they're still hot. If you're eating McDonald's in the car, all you can do is inspect the bag with much of the other contents still in the bag - just shuffle it all around and whatnot. If you've taken it home, or to some other non-car location, you can empty the bag of all contents and you've got clean and easy access to the fries - clean 'em up.
