Taxi in Belfast

I'm in Belfast and there is a connection I have to make to get to the Ferryport, but I can't be bothered waiting for it, as I got an early bus, so I decide on a Taxi, so I approach the Taxi rank outside the Europa bus station, and then this guy says to me 'are you looking for a taxi, where are you coming from?' I tell him 'Dublin' and he directs me to a suitable taxi, and I get in, and it only then I realise, that if I had been a Protestant, I would have had to get into another taxi. How sad is this in the 21st Century?
