Captain Peacock worked as the floor supervisor of the Grace Brothers department store in the 1970's BBC comedy show, "Are You Being Served?", which ran from 1972 to 1985. Actor Frank Thornton played the character of Captain Peacock.
In the show, Captain Peacock looked down on the other members of the staff and greatly exaggerated his military career. Thornton, who died in 2013, reprised his role as Captain Peacock in 1992 for a spin-off show, "Grace and Favour." This series, which ran for two years, followed the exploits of the original Grace Brothers department store staff as they attempted to run a dilapidated country house hotel.
