There should be an app where you can enter your location, and it will tell you what McDonalds has in stock.

You know how sometimes you really want a Big Mac but their website says that one has no buns. You'd drive out of work just to find out they're out of Big Macs? Or how sometimes you just want a Diet Coke but the one by your house is out. <br><br>I think it would be super useful to be able to enter your zip code or some other thing that locates the McDonalds nearest you, and then it will show what menu items that McDonald's has in stock. That way you could plan your day out around which McDonald's has what you want.
