I'm originally from mid-western Canada, but back in 2001 I moved to California and lived and worked there for three years.  part of my job involved updating and editting a website on a daily basis.

My employer was a former school teacher from New York.

Can you imagine how often he lost his mind at my "Canadian" spellings?

Let's not even mention the huge learning curve when I had to go from Metric to Imperial.  I still can't wrap my head around fahrenheit!!

The funny part, though is the accent.  For the most part no one had trouble with the way I spoke.  Most people thought I was a native Californian.  There were a few words that I pronounced differently.  "Pasta" stands out in my mind and I always grew up saying "pop", but down there it's "soda".

Oh, and when I'm under the heavy influence of intoxicants, apparently I say "eh" a lot. LOL.
