Hi, I will be heading to Ireland soon and was thinking about the toll roads. Several years ago we were over there in the car and ended up on toll roads and came off again without ever seeing ( might have been there and I missed them ) a toll booth to pay at. We were told later that you need to go into a shop to pay. Did I just miss something obvious? We are not planning to use the toll roads deliberately but if we end up on them we don't want to avoid paying and get a fine. TIA
