A couple of experience with this: Many moons ago a guy who commuted on the same train as I did hit my up about some Amway opportunity. Basically he said I could make enough money to stop commuting everyday. I pointed out that we ride the same train together everyday but that didn't deter his pitch. Finally I accepted some sales material to shut him up. Over the next couple of days, dude was on me to go to meetings, etc. I handed him back the unread brochures the next time I saw him and he was butt hurt, like really personally hurt! Creepy. I started to ride further back on the train to aviod him. More recently a friend/ex-coworker approached me about this and I knew the only way to nip this in the bud was to be direct but not harsh, after all, we were friends. Anyway, after emails and phone calls and happy hours, I just told her to knock it off already, it was ruining happy hour, for cryin' out loud! I wasn't mean, I just said it was enough already. Haven't spoke to her since. What is it about the cult like dedication? They seem to take rejection personally not professionally.
