Some people change their dealings with people once owning a business. It is wrong. It is a sign of arrogance and immaturity. Why change the attitude once having a business? Do you expect your business to grow without people buying your products? It is a shame if act that way. Recall those days when you were struggling to find money and the day you created your business, those people you neglected were there with you and were your permanent customers. Never expect them to like you after changing your attitude. Don't forget the power of the a boomerang.
