Sounds like a great SA experience! If I eventually become an SA, I would be just like that guy at Sephora, and I would mention Basenotes to my customers.
BTW, did that Sephora start carrying Thierry Mugler fragrances yet? Sephora's website shows that they're now carrying Mugler again after a 2-year hiatus. Not sure about the retail stores, though.
Speaking of stores, many Macy's (and soon-to-be Macy's in 2006 post-May Co. merger) stores are starting to carry Mugler...a significant percentage of the chain, in fact. After all, some of the Macy's West stores and a handful of Macy's Central and East stores carry Mugler, along with most Marshall Field's (soon to be Macy's North) stores...soon, nearly the whole chain will.
