I spent some time in Ukraine awhile back. Everyone was rude to everyone else. The only time a woman smiled to you was if she was trying to sell you something or if she knew you.
The cool thing is that no one took it personally. It was just the way it was.
I got so I would elbow my way up to the Simferopol McDonalds and just say "Get the F out of my way" and no one cared.
Unless if they spoke English, in which case it got quite ugly.
The point being if people are rude, it should encourage you to seek a zen moment and become one with the universe.
Especially if they're Ukrainian, carry grudges, and own heavy equipment (reference to the Italian Job).
