I have regularly told my ex-dope man this. He wasn't using heroin himself, so whenever I did this (most of the time this would happen because he would have someone do the dealing for him, some of those people tried ripping him off) - he would actually thank me (so he could put an end to whomever was screwing him), and then he would get me free product to compensate for the hassle.
best dealer ever?
