The London traders who deal exclusively with honey are one of the oldest groups in the city and have been trading there for almost 1000 years, with traditions going back to the very earliest days of trading. Their trading floor is actually situated in the Bank of England and still retains the original hexagonal tiles that mimic a honeycomb. They wear distinctive black & yellow horizontally striped suits with matching hats and have also developed their own trading language that consists mainly of Zs. For example, buy is Zzzz and sell is Zz.
