Ive only been to a MAC counter twice. Both times Selfridges in Oxford St. The first time I was looking at e/s not for very long & I was asked if I needed help. The girl was great, really helpful! She suggested a few other products for me & helped me choose a blusher, trying some out on me etc. It wasn't exactly empty in there either.
The 2nd time it was absolutely packed as it was the day after Fafi was released. I was looking at lipsticks for ages, trying to find Plastique but I wasn't offered any help. However, like I said, it was packed & it wasn't as if all the MA's were standing around doing nothing.
Also like to add that I look about 15 & rarely wear makeup when shopping dressed in jeans & trainers
