It's something that can be very noticeable in fanfic. The Americans, not surprisingly, can get a bit upset at rude remarks from British and Australian fans about B7 characters speaking American - they don't understand why it grates so badly, because the language sounds normal to them.
And the solution is so easy - a good British beta reader. Mind, it works the other way, too - I've seen some dreadful Briticisms in Buffy fic as well.
