(Photograph) - Pure genius: Sharon Helina, lecturer in languages at Airedale and Wharfedale College in Horsforth, tells a regular at the Cardigan Arms in Leeds about a course on ordering drinks abroad. Customers at five Tetleys pubs in the city are being invited to sample a range of free courses with their pints this week. Samplers of courses such as calligraphy, local history and crafts are available as a pilot community education project.
