My experience with SAs/MUAs at MAC have been overall positive, the best being at my Pro store. I try to make most of my purchase there if I can. I did have a not-so-great experience in Mykonos, but it wasn't a freestanding door, and I'm not sure I would consider it an actual counter. I allowed the SA to dissuade me from purchasing Red Racer because she was being totally overbearing. I should have bought it anyway because I obsessed over that lipstick once I left. Luckily, I got it during an online restock.
