You can call me a sexist if you like, but from my personal experience in our Apple store the girl salespeople don't know anything. Anytime I ask a question their answer if very vague or completely wrong. Plus, this lady was about 60. So I knew she wasn't going to know anything about Photoshop and wasn't easy on the eyes.
So I went to the guy, not because he had a big package or anything. Simply because I believe he was going to know more. He did. He was also a part-time Graphic Designer and showed me his work, told me features about the Macbook Pro compared to other models.
Don't get me wrong, if the girl who approached me was mid-twenties, good looking, and actually knew what she was talking about I would of happily spoke with her.
