La de da oooo ar, aren't i powsh. Cup of tea ey what?
It's definitely not a problem at all, i love the accents! I can't spell for instance,
that's a problem!
Bad example, but funnily enough my dad couldn't understand my mum when they first met. She's Scottish. Much like the Irish character Brad Pitt played in “Snatch”; you only get a hint of what is being said!
That's a problem due to a completely different language being spoken, way too quickly, with "fun" pronunciation; so it's not really an accent!
