I'm certain that it must be just one single incident and not typical for the normal hiker to steal food.
At least it is very seldom here in Norway, and I have not heard that we are exceptionally honest. In addition we have a lot of tourists from all Europe. The reason for saying this is that we have a quite unique hut system and some of the huts are even equipped with a depot of food for the hikers to use, and these huts have no staff to collect money from the tourists. You take what you want and pay when you are back home, noone controls you, it is based entirely on honour. About one third of the huts have this food supply without any ward, you see them on this map http://ut.no/kart . They are marked with a red/white square. We call them selfserviced huts.
