Recently I've flown with ANA, and it looks like they're really short staffing their flights. I can't imagine being treated the way you did, but if I felt ignored I would have piped up at the very beginning.
They are indeed short staffing their flights, and I believe JAL is in a similar situation though I haven't flown with them lately. The cabin service is taking a long time and I expect it will be even slower once they start charging for things. It's still better than, say, United or American.
