BBC News Actress Mollie Sugden has died at the age of 86, her agent has said. The TV star, best known for playing Mrs Slocombe in long-running BBC sitcom Are You Being Served?, died at the Royal Surrey Hospital after a long illness. I loved Are You Being Served. I first saw it in the US as one of the local PBS (US BBC equivalent) stations ran a Britcom night on Friday nights. There aren't too many of the cast still alive now.. RIP Mrs. Slocombe!
