I had the opposite when a new quilter needing help and LQS had snooty unavailable staff as I prepared for one of their classes. Maybe a strong "I prefer to browse alone and request you respect that. However, if help is needed I'll be sure to ask for it." This person may believe she is doing what's expected of her. I understand your complaint as I hate hovering staff and leave immediately when that happens. I hope this owner/staff comes to understand your request, maybe if she knew she was loosing your business she would get it. Good luck.
