I used to work at Nordstrom's, so customer service at a clothing store (or any store for that matter) is kind of a big deal for me. It really is an art to be helpful without hovering, and I appreciate an eye that desires to dress the body, not judge it.
It's too bad that you weren't helped well enough. I reward my business with good business people, and I let them know it. I love being helped, and am on first name basis with some of the sales people at my favorite stores. Let them know they dropped the ball.
The only place I had a serious problem was Urban Outfitters. The bitch totally deserved an earful, but I was so shocked at what she said that I just dropped all my shit on the floor in front of her and walked out.
