Gatekeepers

I went to an gallery yesterday, there was an artist whose paintings had a very unique color. I asked the gallery person if I could get an information sheet on the artist? I was rebuffed and told "we only give information sheets to people who buy something." This is one of the reasons I sell my own work out of my home/ studio. Man oh man , I get art lessons every day from people like this. What harm could come from me knowing more about the artist? Well it takes all kinds of people to run the art business, I just hope there's alimit on the kind I just described.
