I loved flying with Ukraine International LGW/KBP/LGW, often out of LGW I would get an upgrade to business class as I worked for UIA's LGW line maintenance provider.
But even in economy when they came round with the trolley offering me Carlsberg or Heineken I would ask for Slavutych ... "You want Ukrainian beer sir?" ... "Yes please, can I have 2?" ... "No problem sir" ... I wasn't stupid, Carlsberg and Heineken came in 330ml cans, Slavutych came in 500ml cans and the crew would be so complimented that I liked Ukrainian beer I could go to the galley and ask for more and more
