I m a french ryanair cabin crew based in CRL ! As a crew you are supposed to know not all but almost all the prices of each things on board ( I mean at least foods and drinks) If there is any inflight magazine (could happens) the crew can check the price on the EPOS ! The N1 is supposed during the briefing (before the flight) to check if the rest of the crew know the promotions and prices !
But i understand that this story annoyed you !
It s weird because BGY-DUB is operating by DUB crew and in DUB they are supposed to be so so so so strict ....
