Still, it seems that even those that clearly are solved problem can be done badly. Recently KFC rolled out here. And their kiosk seem to miss the basic options to customize the meals. Like just removing things. Can't do that with meals... Have list of extra options of stuff possibly not even in the product... Actually they don't even tell anywhere what is in their burgers. But I digress. All other chains including the local one manage to have these options present...

So in the end automation won't always solve everything immediately...
