Before we talk about the finger, can we mention the hammer and sickle on her hat?
Even though that finger is clearly not wearing those Mickey Mouse gloves, Tatiana is not really swaying us with the whole "The finger isn't mine! Only the intent and meaning behind it and my hatred of passengers" argument. On the other hand (haha see what we did there?), we are sympathetic to the fact that airline passengers deserve it. They deserve it because they're entitled pricks who will get an air hostess (they don't call them flight attendants in Russia) fired over a stale bag of peanuts, which is unfortunately why Tatiana should have known what would happen. Fortunately, Aeroflot still has 1300 blonde air hostesses named Tatiana left.
