I feel credit-cards-as-credit is mostly an American thing, basically everyone I know in Europe treats their card effectively as a debit one, the only difference being you could not rent a car with a debit one. Some people don't even know the difference and get surprised when their card cannot be used for some credit usages. (That is just my anecdotal evidence, of course)
