This is how Britain's New betting-shops will work when they become legal on May 1st; "Clients" - members of the staff, - are seen here as they take part in a "Dress Rehearsal" for the big day in a typical shop above a small caf?just of Fleet Street. The "Clients" are handling over their betting slips with their money to the bookmaker's clerk-behind the post-office like Grille. Their slips are time-stamped and numbered tickets are handed back to the customers. 26 April 1961
