I think nurse Kelley reads this forum
If you go to nurse Kelly's FB page, she has a post from yesterday addressing someone taking pictures of her clients coming into her spa, claiming they were just "taking selfies."
Whether or not that is true, given the earlier post on here about someone taking pictures of her clients, I think it's safe to assume she reads this board.
But weather or not someone sees you walk in shouldn't matter. She also runs a legitimate spa business. They don't know why your walking in there. For all they know you could be getting a wax or manicure.
