NTA ruling on PUC :
"Booking fee of €2 may be charged for any method of engagement other than engaging at a taxi rank (including at an airport or other transport station or terminal) or hailing in the street. Such circumstances include a booking made by telephone, email, smartphone app, fax, text or letter, or a booking made through a telephone call or a personal visit to a dispatch operator’s office"
Surely you cant be penalised by a dispatch operator if you apply the law of the Taxi Land ?
