Went on a retaining customers by super customer service course provided by Welcome to Yorkshire. To be fair I tried to go into the thing with an open mind but was not particularly wowwed. The best complaints training I have ever had was with the Inland Revenue who due to the nature of the business is almost entirely complaints. Plus once you have been told at full volume that you are single handedly destroying a man's business and destroying his life there isn't much that can phase you. After two years there I developed hide like a rhino which has stood me in good stead for my hospitality work.
