On a recent trip across London, one Euromoney journalist discovered an advert for a game in a booth on the banks of the Thames. The name of the game? Whack-a-Banker. Although the booth was closed, preventing a trial run at the game in the name of research, it is to be hoped that the (presumably three-armed, if the picture is to be believed) assailant depicted on its shutters is not in fact loose in the Square Mile.
