The Many Duties of the Stanners
The Worshipful Company of Stanners, a livery company, was founded in 1321 to recognise a form of civic official unique to London. "Stanners" were - and still are - licensed to make arrests, practice as a doctor, conduct weddings, advise on astrological issues, divine for wells, issue financial advice, hunt deer within city limits and sell pamphlets and newspapers.
In order to provide these services to the general populace, they stand in little kiosks around the city - generally near Tube stations - and announce themselves by shouting: "Stanner! Stanner!"
