I work in Ian_Gile's area and he'd be right when he says £8 is the max what you'd get for a 3 bed semi.
However, I quoted for a posh 3 bedroomed semi this morning and received a load of verbal abuse from the Northern Irish customer. Whilst looking round his house, I said I'd spent several years in Northern Ireland, as a soldier, and my first wife was Irish.
When I said £10.00, he asked, 'how often?'
'Every calander month', I replied.
'Every month! You F****** C***, you've spent too long in Ireland, you B*******'.
I was really taken aback, but saw he was laughing. He coughed up then and there and we cleaned his windows.
Later, while during another house he walked past and I asked him what he thought of the job.
'F******* spot on', he said, so I guess we've got him in the bag!
