Query: Very good with one complaint

I'm an intermediate-advanced Japanese speaker. I'm always trying to improve my vocabulary. This book is great for learning common phrases that you probably wouldn't learn in a class or normal textbook. I have heard of many of the phrases already. There are a couple that I didn't know and I asked my Japanese friend if they were common and not old-fashioned. (I'm always skeptical if books are using outdated terminology.) She assured me that they are common expressions used today.My main gripe is that Kanji and romaji are used but not furigana. This is surprising because the sentence examples use very difficult vocabulary, much too advanced for a beginner, but only a beginner would want to see romaji.Otherwise I find it to be quite helpful.
