I have been doing extensive book research in the field (my restaurant) and in scientific journals. My tips have been astounding my coworkers.
The book will answer questions like
How can acting like an ape increase your tips?
What short term investment has a 1,300% return?
How fewer choices mean bigger gratuity.
To celebrate, anyone who has left a comment on my site or signed up for the Soule Opportunity Network will receive a free copy of my book on the release date.
