Guarantee to You
Charles Grimes always offer his clients a 100% guarantee of satisfaction.
He is totally convinced and certain that all delegates will be delighted by what he does and will see significant benefits to the team and to the organisation. Therefore he is prepared to accept the full risk of the session.
What this means in practice is that, if at the end of a session, people are not completely satisfied and can see no benefits, then he will simply take back the materials, shake hands, and you will owe nothing whatsoever.
