Yay to Ian's last post.

Let's look at it like this. If a social worker who worked with anorexic patients also happened to be an Avon representative, would it be appropriate for this professional to leave cosmetics catalogues with people on his/her caseload?

This is an extreme analogy... but card carrying believers get some type of personal if not monetary reward for reaching and making converts.

So to my mind not that different.
