In spain we have a mix of both; although it is very normal to say it formulaically to e.g. a shop clerk, we are also very often very direct and don't use it, just using tone or phrasing - and foreigners (including spanish-speaking ones) are usually shocked by how rude we seem to be.

I've found that Greek translates pretty much exactly to Spanish (culturally and linguistically), so I just say "puedes traerme <x>" or, at most, "quisiera un <x>".
