I had a nice experience in both Paris stores (Faubourg S-H and Left Bank) this spring. Helpful staff, let you browse, showed merchandise, answered questions and (wisely!) did not force me to speak French.
The Barcelona store is tiny and was overrun with Asian tourists when I walked in. The staff was very overwhelmed, but never missed a beat. They made eye contact with me and sent the non-verbal message that they knew I was there and would help asap. I have nothing but nice things to say about them. Very impressive under pressure.
The Honolulu store was wonderful, too. Likewise, Rome and Milan.
On the other hand, I'm finding the Chicago store to be unbearably snobby. And I've shopped there for decades. It seems that since they have moved to their new location, they've become quite full of themselves. The staff used to be so lovely, and often I'd make a purchase just because the sales person was so nice. So disappointing!
I had a similar experience at Chicago and was underwhelmed. While one SA was friendly in kind of an insincere way, a large group ignored us as we had a browse around both levels. It was a slow rainy day, you'd think they'd want the sale. Fortunately, my home store has been wonderful!
