I have got a number of taxies from Dublin Airport and had the usual complaints of having to wait two hours in a queue (when I tell them where I need to go) and how pressed they are since de-reg.
So now I have chosen to withdraw my custom. When I arrive in Dublin airport I immediately telephone a taxi company and arrange a pick up from departure levels from my regular taxi company whose drivers have no probs bringing me from point a to b without complaining. There is no waiting in a queue as the taxi does be there waiting at door two at departures level by the time I get through arrivals.
I would suggest that other passengers do the same!
