Not fast food though. We have different expectations at different types of establishments

Fast food prices are pretty sticky. We consumers don’t like anything changing or being dynamic. But it is was a communications failure. If they slowly raised the prices then announced time based discounts, like how a happy hour works then it probably would have been fine. Sonic does this. But dynamic and surge pricing means I never know what it’s going to cost until I’m ordering. That’s obviously a stupid strategy for budget dining.
