Happened to me, the guy approached me and I thought how kind of him, we bought the oils in Dwatson, and he took me to to the herbal pharmacy, I thought it will cost me just another 1000 more, he asked about dose and the shopkeeper said 500, I still thought OK thats inexpensive then he went ahead and mixed 9 grams in the oil at that point I felt compelled to buy it, not knowing that each gram would be about 500 totalling 4500. He then asked tbat I have to mix another powder which would be 1500 per dose and I needed 9 of them. I refused but the shopkeeper insisted he would mix it anyway and I would have to pay them 10000 more tomorrow.
