Dazmond (as usual), clearly hasn't read he first four words of the second line.
Our work is an exact mix of yours I have one of my first ever customers paying 50% less than one of his nieghbours, he's a real nice guy, generous at Xmas,cash payer,never moaned in his life, I recognise that when I was getting going he gave me a start and seeing the van got me several more on his street, Most of the clearly underpriced jobs are long standing ,generally elderly customers who have done you a favour of sorts,( recomendations,intro to family members,nieghbours,etc) through a sence of loyalty these custies get a good deal, Thats how things work in a face to face working enviroment and you should see it that you are a kind,generous hard working guy with some empathy for people.
