Variable pricing on uber or flights makes sense because people value their time or schedule flexibility differently and there is finite or slow to change capacity. An executive cares more about minimizing travel time than a student so they will pay more for the most convenient flight. For restaurants, a "happy hour" might make sense to bring people in off-peak. But trying to charge more during peak hours only works if I can get my meal faster because all the price sensitive customers are gone. Maybe I don't eat enough fast food at peak hours, but that's not a pain point for me.
