In the scene where Elle has just found out about Vivian and Elle's-ex and she goes to go get her nails done. She sits down and says, "Are you free? It's an emergency." And she places her hands in the water in the bowl on the manicure table. But when the camera switches angles and shows the nail lady saying, "Bad day?" Elle's hands aren't in the bowl, but when they show Elle again from a different angle, her hands are back in the bowl. She has some pretty fast hands!
