Translation of prick in German

We decided to fly directly to Hanoi and booked a flight for the same day. Before we left we still had some time to visit the War Remnants Museum. One could see the former headquarters of the South.
The name of the agency was Handspan and they were the first ones in the country that worked under ISO 9001:2000 quality management. That was pretty convincing especially after our horrible experience the day earlier.
Fortunately and against all odds there were seats available so that we changed our booking to the same day. Our destination was El Calafate in the South of Patagonia in order to see the glaciers.
