SunQuilts

I send nearly all of my quilts to the same LAer I have used for years; she does good work and is conveniently located from where I live. However, one thing over the years has bothered me considerably. When I am binding a quilt she has done for me, invariably I find several knots/tangle/loose ends of threads in the quilting. I can't just cut them off lest the quilting unravel. I end up taking the quilt back to the quilter for her to deal with it - which she does. But it is frustrating to me to always have to make another trip as well as worrying that I am missing some areas that need addressing. My question is - shouldn't she be inspecting the quilt backs to pick up on these things before I pick up the quilt? And lest you think I am being really demanding, I could live with an occasional missed tangle but when it occurs regularly and often multiple times on each quilt, I am bothered. Any advice? I hate to change quilters - we are friends as well as having a business relationship. But this is getting to be a real problem.
