Apart from bad signage, no seats, and filthy tables in restaurants,
Manchester airport security are racist toward Irish people. In terminal 1, they're so ignorant and dont even know that Northern Ireland is in the UK! They tell you to join the queue for ROI flights, only to end up in exactly the same place where the end of the UK queue is at the conveyor belts.
Fat, useless english police then walk past and make comments such as, "Oh not more paddy b*st*rds", which I have heard along with many others. ABSOLUTE CIRCUS, COULDN'T MANAGE A P*SS UP IN A BREWERY!
