> why would I ever want to lower my prices if customers keep showing up? I've noticed that restaurants that severely raised prices have gone from a significant wait time to being almost empty while those that raised them a more reasonable amount have gotten closer to packed. So I'm not sure I really agree with your assumption that customers are price insensitive. Besides, it's pretty short sighted to talk about "still showing up". If you want to maximize profit, you need to guess at how many would show up with lower prices.
