If you go to a support group and someone from the group approaches you about an "outside" income opportunity!

I find it offensive that someone would try to promote a new product that they supposedly use themselves and also try to recruit me to sell the product when support groups are supposed to be a "safe" place to go without fear of being solicited in such a way. What would be a proper response in dealing with such a person without causing hard feelings since I have no desire to try the product or become a salesperson?
