The ridiculous goings-on at Grace Bros. have kept audiences laughing since 1973. This tongue-in-cheek farce, by top writers Jeremy Lloyd and David Croft, is one of BBC's best-selling classic comedies, especially in America, where its success is phenomenal. A large, old-fashioned department store in London, Grace Bros. is still run on strictly hierarchical lines. Each member of staff knows their place -- in theory. In practice, they are all engaged in their own private wars with management and with each other.
