I find this a bit odd as you make it seem as if ordering is a complicated process that takes some thought and planning. The whole draw of McDonalds is that you get the exact same food wherever you may be and their options are fairly limited. Ham/cheeseburger, chicken burger, fish sandwich, or nuggets is pretty much your array of options.
I personally dislike the ordering screens as they make the process way to drawn out. Let me just pick a #1, the size, and the drink and be done with it in 3 taps. Last time I used one, it wanted me to basically build my own meal as if I was ordering Dominoes online and building my own pizza.
