I agree, definitely push the issue, if the house is as nonchalant about it as you say they are, I would have bowled my last game in that house. I had two long, deep scratches in my Inferno in my track a few weeks back in a Brunswick owned house, and the pro shop operator took one look at it, and said "can't fix it, what weight, I'll have a replacement ordered tomorrow." Now that is customer service, it shouldn't take an argument to get what you are deserved, but I certainly wouldn't go down without a fight on this one.
