* Παρακαλώ (parakalo): This is the most common and versatile response. It means "please" but is also used as a polite "you're welcome" or "don't mention it." It's generally the best and safest option.
* Δεν πειράζει (den peirazi): This means "it doesn't matter" or "it's nothing." It's a suitable response if someone thanks you for something small or insignificant.
* Σας ευχαριστώ κι εγώ (sas efharistó ki egó): This translates to "I thank you too" and is a more formal and reciprocal way of acknowledging the thanks.
Therefore, παρακαλώ (parakalo) is the most practical and widely accepted response to a thank you in Greek.
