Yeah but it's more like the prisoner's dilemma vs. the iterated prisoner's dilemma. Some people think that what makes the modern world work is hyper-optimization, but what really makes the modern world work is reliability. If my counterparty, the hamburger stand, is trying to hyper-optimize their profit by doing dynamic pricing, now I have to run my own optimization loop to find the best value hamburger stand for that particular hour, and maybe I don't want to waste my time/energy trying to figure out what the best hamburger stand is at any given moment, so I just go to the one that charges the same prices all the time.

Wendy's doing this almost seems predatory. They know people will show up and not pay attention to the prices.

I do, however, like the idea of surge pricing for sit-down restaurants. If restaurant prices raised to guarantee available seats (like hotel rooms), there are plenty of instances where I would pay a premium to eat near an event I'm attending.
