I have had to palm read twice. My first experience was a total scam. I went with my grandma, who was dying of cancer, and some how my grandma relayed that information to the palm reader and she took full advantage of my grandma. She convinced my grandma that she needed to pay to buy a special rock and carry that rock around for a week, and then bring the rock back and pay her to read the rock with her energy on it. My grandma was literally dying and had hope for everything, and this women completely took advantage of her. The things the palm reader was saying to me were so off. She would ask me a question and ask if I could relate to something, which I could not, and then she would get frustrated when she couldn't catch me on something. My second experience was even worse, probably because it was a palm reader on the Wildwood boardwalk. I won't even go into talking about that one. From research and my personal experiences with palm readers, I believe that they truly are a scam and people should not be spending thousands or dollars, or even $15 on them.
