Red Caps, the guardians of London's West End, are encouraging shoppers to bombard them with annoying questions. A new poster campaign invites visitors to ask Red Caps for information about the shopping area, and carries the slogan 'You'll find the world in the West End - Ask a Red Cap!' The month-long campaign broke last week, with posters in Oxford Street and Bond Street tube stations bearing questions, such as 'where can I find a loo?' and 'Where can I find a de-caff skinny latte?' The New West End Company-backed scheme aims to raise awareness of Red Caps and their role in helping visitors, retailers and residents.
