McDonald's: You buy more from kiosks than a person. So expect more kiosks

I think that one reason for this is their new fully electronic menu boards. They rotate through segments of the menu, never displaying it in its entirety, and some items aren't even displayed at all in a recognizable manner.

For example, the only way to find the price of an a la carte sandwich like a quarter pounder is to look in the meal deals section and recognize that the lower price displayed at bottom left is the sandwich-only price... and only when that panel is visible during its 1-in-3 rotation.
