When someone from Britain speaks, Americans hear a "British accent"...

[muldoon]

Americans consider having a "British accent" a sign of sophistication
and high intelligence. Many companies hire salespersons from Britain to
represent their products,etc. Question: When the British hear an
"American accent," does it sound unsophisticated and dumb?

Be blunt. We Americans need to know. Should we try to change the way we
speak? Are there certain words that sound particularly goofy? Please
help us with your advice on this awkward matter.
