Are they very commission driven? I always find they give you the hard sell. I went in yesterday to buy some foundation. I had tried various department stores but it was out of stock so Space NK was a last resort - honestly the woman wanted to sell me about £300 worth of stuff. I felt horrendous when I came out but when I looked in the mirror my skin isn't that bad, I did have dry lips but my eyes weren't half as baggy as she made out. I said I liked Burt's Bees lip gloss and Clarins Marula Oil face wash and the assistant went "hmm" and sniffed.
