To which do you think Russian Patriarch Kirill meant to treat Ecumenical Patriarch Bartholomew, Novichok or polonium?

The video shows the meeting of Ecumenical Patriarch Bartholomew and Russian Patriarch Kirill held in Instanbul on the issue of granting the Ukrainian church a tomos on autocephaly – the move Moscow fiercely opposes. When a security operative from Kirill's delegation started offering drinks, he first approached the Russian Patriarch, and when the latter reached for one of the glasses, another security guard rushed to guide Kirill's hand away from the glass, helping the Patriarch make the right choice. Patriarch Bartholomew's reaction to this confusion was rather restrained but unambiguous: with a clear gesture, he refused, and so did all the other clerics from the Ecumenical Patriarchate.
