Averaging prices over expected volumes is inefficient though: you're essentially screwing some people over to recoup it from others. Why not true price if you have the ability? Previously, it wasn't possible because of printed menu costs. Now it is. And I feel like food prices can absolutely be elastic, with a notification method like app pushes. If the local Wendy's says they're selling burgers at $2 because they're slow today, more people might decide to go. And critically (and what this is probably really about) they can reprice in real-time in relation to their neighboring alternatives. I.e. McDonald's across the street discounts their cheeseburger, Wendy's can mimic That's what this stuff is really used for when retail adopted it.
