Stamps when leaving EU from Athens airport

Kelispera!

Has anyone recently been stamped out when leaving via Athens airport? I arrived in EU before EES was fully (8 April ) and French being French didnt register me and just stamped my passport, I would require an exit stamp for my future visa applications (other than EU) as I am from a third world country and to show them as a proof that I left schnegen zone on time and didnt overstay
