At the beginning of the movie, there is a scene showing Lynn calculating the cost of commuting to the private school she toured. The movie showed a pile of public transportation tickets that clearly are marked with a SEPTA logo, which stands for Southeastern Pennsylvania Transportation Authority. SEPTA runs in the Philadelphia metropolitan area. Half a minute later the movie identifies the city Lynn and dad live as Seattle.
At the beginning of the movie she calculated the cost of her commute, they show a pile of SEPTA(Southeastern Pennsylvania Transportation Authority) passes but immediately after it shows the movie is set in Seattle. As a Philly native it was noticed immediately.
