Sorry this is slightly irrelevant, as im south yorkshire, but.....
A while ago, i lost a customer down to them moving. Eventually someone moved into the property which was bought and rented out. It was one of many that i do on this particular street. As i was cleaning the neighbours windows, the chap came out asking for a price. His origin is that of bartering for a price. I told him its £10, like most on his street. He tried knocking this price down saying he only worked part time himself and his wife was a stay at home mum with 2 small kids. I laughed, and told him i have worked this street for many years and ive not seen anyone else only work part time to have a merc and bmw parked on their drive and your quibbling a tenner. I should put the price even higher as i work full time and cant afford a merc for my stay at home wife.
He ended up doing a midnight fly off, 2 months in arrears with rent and plenty of improvements needed on property before it was rented out again
