Portuguese People

Why don't Portuguese people ever apologise ? This is not just my opinion but also the opinion of a lot of my friends. I should say from the outset that I think the majority of Portuguese people are really nice, but it really annoys me when something goes wrong and they don't apologise when it is clearly their mistake. This is with companies and individuals. In my culture, you simply say sorry, everyone is happy, and you move on. But not here ! Am I being unfair ? what do you reckon ?
