Alright, take it easy. Jeez. It's discussion, not flame war.

If the reader gets the cards (order of draw, side of flop, whatever variabiles that might count) without meeting me in person or knowing anything about me, then the reader will probably won't be able to tell jack shit about me.
I've done readings for people I've never met and it seemed to work for them. And of course, my readings are not as simple as the example I gave. And... the example was a simple reading, a detailed one takes a lot of time.

Once again, depends on the reader.

(another thing I've noticed is, if you dabble in Psychology, you can do tarot readings. o_O)

You need to experience a reading by someone who can do it. It's not all that bad. And it's for FUN, why get worked up over it? If the reader did nothing for you, just let it go. It was your decision to go to some random 'tarot girl'.
