Just great.

From the Irish department of foreign affairs:
"The embassy recently received notice that there have been a spate of robberies from people who get the flat rate prepaid taxis from Guarulhos airport in Sao Paulo, where you pay and give your address to the desk inside the airport. Someone seems to be accessing this information, and the robbery occurs when the taxi arrives at destination. If using this service, it is suggested that you either identify in advance a hotel in the same area as your accommodation and give that address to the desk, only giving the correct address to the driver once you are en route. Alternately you could pre-arrange transport with your hotel or business company."
