It definitely depends on the couple. Currently, I am working and my spouse is not. During our most recent talk about budgeting a few months ago, we took this into account when figuring out appropriate amounts of fun money for each of us. Specifically, since I am out of the office/house for lunch/dinner less often, and my hobbies (programming/baking) are inexpensive, I neither need nor want as much fun money, and I would rather they have it available instead.
