This is a great method for any kind of impromptu situation with a shuffled and borrowed deck. You
pretty much need no skill for this. It is mainly about the presentation. The only people who might
have issues with this are people who have issues with their hands (like Arthritis), but besides that
it is very easy.
Personally I think it is maybe more a fooler for magicians, as this is a very
clean method. Not sure if it makes a major difference for a layman, but in general it is a very
clean method for the classic "pick a card - let me find the card" plot.
