For anyone that works with livestock, having long guns mounted in vehicles and handguns on one's person is absolutely normal, routine, and safe. Maybe in your country, but in a farming country like New Zealand your farmers and hands generally don't have to leave the house armed to the teeth.
Cows and sheep, generally, are not mutually armed.
Also, owning a pistol in NZ is hard enough let alone leaving the house with one - concealed or not.
If it was in Australia us New Zealanders would simply walk over the harbour bridge and say "Oh hi, I upgraded your RAM" or something equally pithy.
