Mediums and tarot readings I think it's like getting mugged?

I went to a tarot reader. She was dodgy, vague, only told me about things I had told her. Said some mumbo jumbo, was really off about most of what she said. And then contradicted herself and changed tack when I corrected her. I left with a headache and an emptier wallet. Tell me anyone who's had a profound experience at tarot reading. Or who's caught a tarot reader out making up crap.
