Guinness leaving Dublin

I think you are mistaken.. Diageo do not own Burger King. As far as I know it was owned by them at the time Guinness was taken over by Diageo, but that was sold shortly after this.
 
Just let us be glad that diageo have enough confidence in us to invest so much money in Ireland....
Yeah - thankfully somebody still has confidence in our nation's ability to put away a lot of gargle.
