Curious.
At work in a Japanese office when people thank me for finishing a piece of work or something, I never know quite what to say. I have the classic いいえいいえ！ and the book I keep on my desk I refer to has どういたしまして as the most casual then the next step up is way too much something like 役に立てて光栄です。 which is way too hard for just office talk.
What do you say?
