I took to "no worries" fast when I was in Canada because the intensity of the thanks you get for minor actions in North America was overwhelming for me at first (before I realized it was a nice façade that helps smoothing the social rapport). I remember my first few days working at a tech shop in the suburbs of Vancouver, I made a pot of fresh coffee and told one of my colleagues so that he could get a cup had he wanted to. The way he thanked me, you could have sworn I had cured cancer or something. It made me feel like it was WAY too much for just being a decent person (I want coffee, I make a pot for everyone) that "no worries" was very handy, a way of saying "You don't need to put too much heart in your thanks, it's nothing really, I feel it's bordering on praise and I don't think it deserves it".
