I've lost count how many times I think I've scored a really good job only to get the run around after a good few months or sometimes less.
The last one was a £12 000 000 place. Believe it or not, it only had 5 rooms but to give an idea of size, you could have built a 2 bedroom modern house in the hallway. It was a converted old barn with bits added in an acre of landscaped gardens that was nearly a mile down a windy pot holed single track road. These people were the other side of millionaires. The husband owned a well known company that makes toasters, kettles, coffee machines and the like.
It took two of us a knackering 7 or 8 hour day to do the insides and out and these were all easy to get to windows and no ornaments to work around when doing the insides.
To start with the lady was more than happy. She was so pleased to have her windows clean. After about 6 or 7 cleans, the lady started the 'not tomorrow' routine, then it changed to 'not this month'. I kept asking her if she actually wanted her windows cleaned and she kept saying she did, but 'not this month'. In the end, I just simply asked straight, did she want me to call again and she sort of said no, not really, so I didn't.
I've had exactly the same thing happen with other mega rich people. I don't know why though. They seem fine with everything but after a while, they seem to change their minds and become reticent about window cleaning.
