Oh hon, all of us experienced this at one time or another. You just have to go in there with the knowledge of exactly what you want, smile, dress nicely (you get better service--believe me), and feel open to other suggestions that the SA might have for you (but you don't have to buy anything that they push, just keep to your list if that is what you want). Make it a FUN experience and don't be nervous!! We all have your back here!!
