Today I was getting help from someone behind a counter and when I had handed in my form and shown my ID, I wasn't sure if I needed to do anything else, or if I was free to go. Usually in that situation I say something like "いいですか？" and the employee quickly lets me know if I'm still needed.
But this time the employee asked me "いいですか？" before I had the chance. I took that to mean that we were finished and he wanted to know if I needed anything else, which was fine, except that I wasn't sure how to respond. I wanted to say that if the form was in order, then I didn't need anything else. I guess I'm looking for a way to politely ask "Are we done?" in Japanese.
