The Italian food thing is pretty common in many cultures, I’ve seen it in a few countries myself and it’s big deal here in Lebanon. My own parents used to be livid about me bringing friends over and not offering anything to eat when I was younger. It’s a part of my culture I’m a bit resistant to doing, I don’t know, it’s pretty intuitive if it’s time to eat or not, and if someone’s dropping by between meals I am totally fine not setting the whole ass table. Maybe a beer or coffee (the good stuff, it’s a nice thing to share) nowadays.

The Dutch food thing has zero resemblance to my culture but it is in line with something I’ve read before about western (at least the description I read was western) food habits. Going completely off the top of my head here. As far as I remember, historically you had one heavy meal and everything else was a smaller meal. I think I was looking up “dinner” vs “supper”. The impression was that the word “dinner” was originally for the big meal of the day, and that “supper” was for a light meal at the very end of the day. “Breakfast” is more of literally breaking a fast than it is a whole meal and lunch referred to a small mid-workday meal.

So I think the idea of temperature might be connected to the size or heaviness of the meal in your Dutch thing.

Or maybe my nerves are completely cooked after work and this is more word salad than word coherent comment.
