I have flown several times with Airzena from Amsterdam to Tbilisi Georgia. This is a funny airline - the only one where one gets a stewardess sleeping besides you in business class on a early morning flight from Tbilisi back to Amsterdam. This has happened already twice. Since the crew is sleeping one can or has to serve him/herself - you can go to the kitchen and pour yourself a drink. Don't trust stewardesses doing it for you!
