I think it might be a game of hit or miss in a situation like that, but I would foremost suggest that is has to do with your vibration about the subject. In other words, you might have had a preconceived idea of what a psychic reader is like, which resulted in an experience that was a vibrational match to that, which then reinforced your idea of the subject.
If you can see where this is going, chances are that a third reading might be just as dissatisfying for you, because you now have become a vibrational match to that experience.
What I would suggest at this point, though, is that you find a way to clear your present perception of the subject, so that you are left with neutrality. You might want to look into a video on YouTube titled "The Pulse Technique" by Deb Cummings, which is a recorded energy clearing transmission.
When you eventually reach a point of feeling more neutral about the subject, it will be much easier for you to redefine your vibration of what an ideal reading feels like to you.
Also, for all you know, the place you went to previously could have been a host of mere phonies. You just might discover something much better once you have retuned your vibration.
Just give it a little patience and allow yourself to follow the impulses of your heart.
