Learn Italian: Arrivederci, dottore, e grazie. - Goodbye, doctor, and thank you.

Arrivederci is polite and perfectly normal for this situation. While there is a highly formal version (arrivederla) that you might use in very official settings, arrivederci is standard and respectful when leaving a doctor's office, a shop, or a restaurant.

Why use dottore here instead of medico?

When you are addressing a doctor directly as a title, you use dottore (or dottoressa for a woman), just like in English. The word medico is used to describe the actual medical profession, so you would use that when talking about a doctor rather than speaking to one.

Does arrivederci literally mean goodbye?

It actually translates closer to 'until we see each other again.' It is made up of a (to or until) and rivederci (seeing each other again). It is a great way to say goodbye to someone you expect or hope to see again.

Is there a trick to pronouncing grazie correctly?

Yes, make sure you pronounce the final e! Native English speakers often drop it and say 'grazi,' but in Italian, every single vowel is pronounced. It should sound like three syllables: grah-tsee-eh.
