Ah, Amway...
Amway was responsible for my first oh-my-God-I'm-in-a-room-full-of-nuts situation. In my wayward youth I dropped out of college for a while and managed a convenience store. It didn't take long for me to start looking around for some more rewarding employment. This regular customer came in one day and mentioned this vague "business opportunity" he was getting involved in. In a "what the heck?" moment I accepted his invitation to go to an upcoming meeting as his guest. We went to this big function hall. You had to practically climb over the speaker's big expensive car parked right in front of the entrance to get in; I think this was designed to fill us with envy and longing for wealth and money. The guy was super slick of course, he came off as a nice version of the Alec Baldwin character in Glengarry Glen Ross.
My skeptical reflexes were nowhere near as developed as they are today, but even then the Amway pitch seemed problematic to me. The first thing that made me suspicious was that the speaker spent only a few minutes talking about Amway products, and devoted the rest of the time on how we could recruit others to the cause and how much money we'd make at it. It occured to me that unless someone somewhere actually sold something once in a while, where did the money come from? Afterward, my host immediately asked, "What was the best thing you liked about the presentation?" You know, to get me focused on the positive. Then he introduced me to a higher-up, who asked the exact same question in the exact same words. That's when I started to get creeped out -- it became obvious they actually train these guys in this stuff, even the casual small talk. I gotta give my younger self a bit of cred for the way I handled things; I remained non-commital enough to escape the evening unscathed, and resisted the increasingly frantic follow-up phone calls I received over the next couple of weeks. I suppose some good came out of it though -- it helped me see how limited my career options would be without a college education, so I went back and eventually finished my degree.
Since then, I've had several friends start in with the tell-tale pitch, which always begins something like "We're having some friends over to discuss a business opportunity." I learned from the seminar that they tell you not to explicitly mention Amway at first in case your guests are "close minded" about the company and may be under the delusion that they are, oh I don't know, a pyramid scheme or something. I always respond with "Sure, I'll come over. But at the first mention of Amway I will immediately walk out and never speak to you again." That usually ends the conversation on the spot.
BTW, I once heard that Amway is the fastest-growning American business in Japan. I have no idea whether that's true, but if it is, I guess you could consider it the long-delayed sequel to Fat Man and Little Boy.
