> if they update the menus dynamically is fantastic Until it's the prices that are dynamically updated. Soon enough they'll use the information collected from your device to look up your income level, how often you've visited in the past, what kinds of things you're most likely to order, etc and use that data to set a price for your menu alone and suddenly you're paying more than the person next to you who is ordering the same thing.
