This doesn't surprise me one bit, almost every city in the UK has a unique accents and then there's people who have a mix. My parents are from South Yorkshire, but I grew up in East Yorkshire, but then I spent a lot of time in Hull which has a long naval and fishing history. So my accent is relatively mild.

However, I'm living in Canada and everybody says I have such a strong accent. Although I've been mistaken for Australian, which I find as rather strange. I know my one worst pronunciation is of 'three' as it invariably comes out as 'free', which in context rarely causes problems. Sadly my 'two' apparently sounds similar to 'three' as I've been repeatedly given one extra of things, I'm not sure if this is a strange form of politeness like the Italian's always trying to serve more food than you can eat, or if simply I constantly have to deal with retarded people when I order food. Although I shouldn't complain, getting a free cheeseburger isn't something I've got a problem with.
