C'mon guys, give her a break! A girl needs to pamper herself with nice things which can be considered as useless for others. There are so many staff that make a girl happy, and yes chocolates, make-up and sushi might belong here. And men budget is much easier to maintain, as they don't need make-up, hairdresser, beauty saloon, accessories, varios types of clothes for various types of events and so on...
And especially when you come to a new country you might be impress of all the new things which are not available in your country and tend to spend more in the beginning. She will get use to it soon.

It's true that had working hadn't killed anyone yet, but why to take risk?
