I have had it happen to me a few times in fabric stores and even other stores. I am exactly like you, I need to spend time looking and usually know it when I see it! Some people want the help and feel like they need it, but it is an uncomfortable situation to be in for me and I am probably too unresponsive and look like a snob. But I don't want to hurt feelings, either. But not getting help when we need it is frustrating, too. All in all, I am nearly always blissfully happy in any fabric store!!
