Gallery customer service

Today I visited several art galleries in Key West,Florida. It was a wonderful experience learning about new artists and techniques. I couldn't help pondering about how good customer service sold the art. While visiting one gallery, the sales associate tagged along with us but never offered to tell us about any of the artists, and then began presuming which works we found of interest. When he decided that we were not interested in buying his paintings, we were summarily dismissed. Both of us commented about how we felt from that experience as we walked away from that gallery. Now compare that to how we were treated by Theresa at the Wayland Gallery. Theresa spent time talking about each artist that we found particularly interesting. She was very informed but never pressured or intimidated us from asking about a painting or glass sculpture. We watched one of their artists paint a lovely oil seascape and watched it to completion. Which experience do you think sold the art?
