1. With my ‘business’ head on (almost) any registered legal, ethical business that’s contributing to our economy is a good thing.  They provide a service, pay their taxes and keep people employed. 
2. With my ‘spiritual’ head on, most of these types of services are fake and taking money from people that need some help/guidance/advice/positive attitude given to them.
3. With my ‘medical’ head on, I believe some people can read/advise on health (mental, physcial, emotional) of others based on some physcial attributes – but these people are few and far between.

The area of palm reading that really bothers me is people that say they can predict the future based on a reading.  What’s the warranty/liability offered when (if) the advice is incorrect?   

I’d prefer to see more professionally staffed advice/counselling/coaching outlets that people in need of guidance can turn to if they need some help (I’m making a massive assumption here that people that turn to High Street/Shopping Centre Palm Readers are looking for help/confirmation of something or another).

I’d expect these types of outlets around Camden High Street, but not in SouthSide or Westfield!
