I don't think they are being racist at all it is only natural to be shocked at the lack of white people. If you went to Africa and it was full of non-black people wouldn't it take you by surprise? Eastern Europe being poor doesn't have mass immigration and I doubt many have ever seen a black person before.
Most of them seemed very nice with the exception of that lad who likened English women to Vicky Pollard. >.<
The only real racism I saw were from white English.
"England is England so it should just be English"
"They do work hard but we should have kept them out"
