I personally compare cooking time to time to go out end-to-end. Even with fast food, you have to drive to the pickup window, wait for the food, etc. It’s easily 10 minutes and you have to do it 1-2 times a day, so 2-3 hours a week. I’ve had fast food joints take 20 minutes to make the food, too.

I don’t think most people analyze the cost like this and they probably like restaurant food more.

It’s like spending “just 10 minutes” on HN everyday, adding up to something significant by the end of the week.
