I once ordered a double cheeseburger meal in France, and got two cheeseburger meals. Probably for the best -- the drink sizes were a lot smaller and they didn't do refills...
Since that experience, I've also used the kiosks at a newer McD's also in France, and it was refreshing know I could order something in English exactly as I wanted it (e.g. burger without onions, substitute barbeque sauce for the ketchup, and extra mayo), and not have to worry about whether or not the order-taker or the person filling the order actually understood me.
