We do all know that there is no generic 'Scottish' or 'Irish' accent any more than there's an 'English' one, right? We mostly get a pretty standard Dublin accent on the TV here, but that's nothing like the way people speak in Cork, Galway, Laois or Kerry (and google Pulp Fiction Kerry for the last one
).
Likewise people in Edinburgh don't talk like people in Aberdeen, Glasgow or Skye, just like people In Liverpool don't talk like people in Brighton. I realised after thinking about it a bit more that it's only actually some Irish accents I instantly write off as timewasters and not others.
Fully agree with the whispery voice - my phone is hung up and the kettle on before they get as far as telling me how my website doesn't work on their phone properly and can I give them details of all the services I do
