I like all of the MAs at the Myer MAC in Chermside (Brisbane).
Morgan (I'm pretty sure that that is her name, she is the shortest one) was my MA (and my sister's) for the most recent MAC Tech workshop and she suggested some really great products that I wasn't interested in/didn't know how to use before. Now I love them!
The two older MAs, Jade and ...ummm, the one who curls the end of her hair well...she has a dark brown bob sort of cut...damn! I forgot her name. Oh well, they were both on one day when my sister and I kept coming back and forth to MAC trying to decide about products/remembering that we wanted to look at something else. They were both very helpful and laughing (with us) at the fact that we just kept coming back and were both really excited to hear that we were coming back for the Tech workshop, which got us even more excited. The one whose name I can't remember invited me to the VIP night (I'm pretty sure that was her, I clouded over with excitement when she invited me so I could be wrong).
Then there is the taller of the younger MAs who I had my first MAC experience with, she was very helpful despite the fact that I myself was rushed for time. She has a very pretty name which, even if I could remember it (I remember that it was pretty) I wouldn't be able to spell it.
I think that there might be one other MA, but I haven't met her yet, but if the others are anything to go by, she must be great too!
EDIT: When I use the words older or younger in this post, I use them loosely, to signify a couple of years difference. Not that any of them are OLD in appearance. I hope you know what I mean!
