It reminds me that I once worked between jobs for a top insurance broker to the trade, and we had a famous firm of accountants doing our year end accounts. BUT we were a specialist firm and they didn't understand the first thing about international insurance. They were costing billions and my boss ended up preparing the accounts himself. Some marketing companies are all hot air with no brains behind their words.
