This is an interesting story regarding one of my rich customer's. Each month I did the windows and got a constant, not you again I have just paid you. I knew them well and didn't want to drop them as I cleaned most of the street and it was only £8 a month. In the end they dropped me and the grass cutter guy which I was glad about, because I knew something was not right.
In the end they had to sell their home and move in with one's elderly parents. Later on I found out the lady had a habit of buying stuff and they had to sell the home to pay off here debt. Young girl has the house now and I'm back cleaning the windows.
What I'm getting at, customers believe we need their custom, they don't realise we have many customers but tend to hold on to them if we clean the whole street.
