At TNI I have gained a lot of experience about people and how you can relate to them, amke them feel comfortable and break the ice with strangers. In 3 months I have learnt more than I would have in years working in a solitary environment.
Though it is really cold going door to door during the winter months and only the driver gets to have the car. If I asked to stay in the car to warm up a bit my boss would say go sit on the bus bench... That defeated the purpose of getting warm and sounded really rude as my hands felt frozen...
