Haha, Zephyr is too busy eating and sleeping and living the dog life. :)
Sandra, you are right, not everyone is a sales person. Not everyone has that kind of personality. And yes, for some it`s a big step just to be out there at an art festival (or trade show or whatever) in the first place.
But my point was that people should push their own personal boundaries. This is how one grows. For the shy artist sitting in the corner of their booth, they should try standing and smiling. For the person who already greets everyone as they walk by, they should try handing out biz cards. To step beyond your comfort zone is to grow and work toward greater success. Growth and success would be a major reason for doing a show like that in the first place.
