Why do people go to restaurants and pay significantly more when they can just buy the ingredients and cook at home? Those damn chefs make my food in 15 minutes.

Just tally up how long it takes to shop, cook at home, and clean up, and multiply it with the rate at $dayjob. I am pretty sure for most people on Hacker News the figure will be significantly higher than at a restaurant, and we would have to adopt a similar working style to bring the cost down, like buying and preparing in bulk, focusing on a few dishes, cooking for multiple people at once, etc.

I am not exactly a fan of this kind of comparison unless one can actually freely allocate one's time, but it is illustrative.

Why do people go to real restaurants, with chefs who actually cook things, when they can cook at home? Possibly the quality of the food, atmosphere etc.

Why do people go to pub restaurants, where one of the overworked staff will put a frozen meal in a microwave until it goes "ding", then slop it onto a plate for you? Probably not the same reasons, and you'd expect a lot cheaper, though not as cheap as the same microwave meal from the supermarket.

Do people go to what they think is a real restaurant, because its marketing has diddled them, but find out it's actually a pub restaurant when they get there, replete with low-effort slop? If they do, I hope they leave a terrible review and don't come back.
