Benim için tarçin bir içki yapabılır mısın?

Can you make the cinnamon deink for me?

Thank you

Keep in mind I´m just another learner, so this is just a try:

Which leads me to a subsidiary question: is this a valid way to make polite requests in Turkish, or do you risk ending up with someone answering "Evet, yapabılırım" and not doing anything?

instead of yapmak I would used hazırlamak
