So I am less that two weeks out. Just found out that 9 guests are not attending. Each has their own excuses and that's fine. They keep asking how much their plate cost is. I honestly think that that's private and would be tacky to tell them. What is done is done no need to cover the cost. I have been avoiding the question or have said it is not needed. They keep asking what the plate cost is. How should I respond? Again I am not expecting anything nor do I want it
