Working it out, around 23 maybe? It was in a nightclub called Ollie's in Belfast, he was in the 'VIP' area which was basically a crap really small roped off area on the main floor with one easy going bouncer at the rope. He was randomly on his own at the time and one of my mates popped over to get a handshake. We all felt a bit cringe when my mate when over but then we followed him over when Rory was chatting away haha. He actually took a bit of interest, asked how our nights were, what pubs were we in before, even asked me what Dublin life was like vs Belfast as I was living in Dublin at the time. When a couple of his mates came over we decided to let him get on with his evening, wished him well and he said told us to have good one. I know thats all common courtesy anyway but he could have ended up being a total dickhead given his position so fair play to him.
