Rockdoc has it exactly right. In the 20 years before retirement I owned a futures commodity business, specializing in agricultural products. I always made it a point to give non customers as much time as possible knowing that eventually they would either become a client or refer others to my firm. I treated traders who got their information from me but had their accounts at other firms exactly the same and eventually many did transfer their business to me, which I knew they would eventually. There is no substitute in business and life to treat the least as the first.
