Maybe one thing you missed out on is that the majority of Poles are very nervous about speaking English to a native, its the fear of not being in control.
The thing is, I'm Polish... my Polish kind of sucked in the beginning, but it's a little better now. I was nervous about talking to people in Polish at first, though I quickly stopped caring.
Plus I don't only mean they're uptight when they're talking to you. It's just a vibe I get, I guess. I can't really explain it. But it's like people are always working on keeping up appearances, and posing. They don't often lean back, sit on the steps and eat a lunch, or lay around in teh grass at the park. Well the last could be because of the aforementioned dog **** problem, but you get the idea.
I would however, like to point out that I have also visited Krackov, Lodz, Zakapana & Wroclaw where I felt most welcome and found Warsaw to be the exception.
That's great, that's how you should remember Poland :) I'm going to Lodz for a couple days to visit before I leave Poland for good. I've never been there, but I want my last impressions and images of my country to be positive.
I agree that Warsaw seems like it's trying to be a big city, but somehow it doesn't feel like it. The service in shops and restaurants is getting better, but I really wish people would learn how to fake a smile even if they're not in the mood. They get paid to service customers, after all.
