Don't get me started on MLM's. I had one kid fight my brother, and cheap shot him because my brother told him "you are not going to retire your parents with vemma"
Personally I run a facebook group for young entrepreneurs with over a thousand members. I have a rule, and a pinned post that clearly states that MlM promotion will not be tolerated. At least once a day someone will come in to pitch visalus or vemma, and talk of a great opportunity etc etc. Ive wasted a few hours talking to these people, and they are not a very smart bunch. According to a vemma "brand ambassador" liquid vitamins are the way of the future due to faster absorption rates. I called him out on it, and told him vitamin timing has an effect that is almost nil, and most water soluble vitamins just get pissed out, and are dirt cheap.
I then probed him for the cost of one can. Over 2 euros. This is more than 2$ American. Typical energy drinks fall below 1$ to manufacture. Food products tend to have lower margins as well. When I asked him why the product was so expensive for an employee I shit you not he said "vemma has aloe,green tea, and mangosteen extract so that is why its so expensive" Ran a quick search on alibaba, and found out that mangosteen extract was worth about a hundredth of a cent. I told him this, and his response was priceless. "Verve uses extract from the mangosteen peel because extracting from the fruit would not provide you with the crucial xanthols"
The conversation went on, and he told me that his mom that is a nutritionist even went as far as putting the drink in a mass spectrometer to test the drink (lol)
Those are just a few instances. These people are very stubborn, and hard set in their ways. When one doesnt work they move to the next until all of their friends, and family dessert them.
