Money changers in the temple...I kid you not.

So on Thursday nights, I work in the Salt Lake Temple cafeteria serving food. Tonight, I'm cleaning up and I see this sweet old temple worker leaving and I make polite small talk. He tells me that he's never seen me before, I let him know that I've been there about six months, and he says how happy he is to see me at the temple. Anxious to get going, I make a polite comment about him having a little snack in the cafeteria before his last session and he lights up and he asks, "Do you feel that you have enough energy?"
Confused and leary, I answer that I'm sure that I could always use more. He then asks me what I eat for breakfast, lunch, and dinner, and I sheepishly make something up (sorry for lying in the temple, but I'm pretty embarrassed by my poor diet). He then pulls out a bottle of Full Energy Inulin and proceeds to tell me what a difference it makes for him in his energy levels. From his pocket, he pulls a plastic spoon out of a baggie and asks if I'd like to taste it and so I do and politely say how good it tastes. Long story short, he asks me if I'd like to try some. I hem and haw and ask how much, and he says, "only 41.99 for a 1 pound bottle." Before I can think of an excuse to hightail it outta there, he says, "stay right there, I'll be right back." He is gone for a few minutes and I consider slipping out, but remember that I'm in the temple and I'll have to see this good brother every Thursday, so I stay. He comes back with a BRIEFCASE full of this stuff, and shows me a very small $41.99 bottle of Inulin (which, FYI, on the website is $39.99). I tell him that I am a poor teacher and cannot afford such goods, so he gives me a gift of a sample size of the following: Silver, sugar-free nutritive bullets made with 100% Inulin
Apparently, I'm supposed to take one of these 15 minutes before running and any other time I need a boost. My question, what is Inulin? To me, it sounds a bit like Insulin, and that's not good.

Anyway, sweet old man. I'm not interested. When I got home, I looked at the bottle closer, and this "miracle pill" is bottled in Holladay, Utah, and the sweet brother's name was Brother Silver.
