If you are 18 years or under I am afraid I cannot offer you a reading.

If you need medical or legal advice please consult a suitable professional!

If the client should feel that I'm not "picking up" accurately  for him or her, and this is mentioned within the first five minutes of the reading, I will end the session, with no charge to yourself, the client.

It is not, however, acceptable to state that you're not satisfied, once you have had a forty minute reading!
