Ireland is not in Schengen, so you were doing an international-to-international transfer. You normally don't have to go through immigration and customs for those, unless there are specific legal requirements or the airport is poorly organized.

Sure, but we went down the same hallway as everybody who was stopping in Ireland. There was just a sign at passport check with an arrow that said go on by. If I had wanted to stay in Ireland, I could’ve just walked out of the airport.
