Many moons ago St Patrick appeared in an apparition to the WGM of Guinness. Following this event it has been celebrated, as you did, on the 17 March. In conclusion it is a publicity stunt for Guinness that went wrong for the world, but a job well done for the WGM. St Pat may I add does not get a bonus, he's in it for the love. St George - who wants to drink a dragon.
