I had a broad Scottish speaking grandfather and I needed a translator.

So what are the worse and best accents ?

I love accents and pick them up very quickly, I was once delivering in Runcorn and had to translate between a geordie driver and a scouse forklift driver both with really thick accents. Lived in Doncaster for six months working with guys from Sheffield and in digs owned by a Glasgow miner and his cockney wife, when i came home nobody could understand what i was saying for some reason.  Common sense isn't very common.
