Dear James.
In order to keep our prices low, we often have to work a longer day. This often entails carrying out the window cleaning out of hours when no staff are around. This is one of the reasons that we have been able to freeze the price for cleaning windows at your premises to £10. If you would prefer us to alter our schedule this would mean extra travelling and would drastically increase our costs in cleaning your premises. We can certainly carry out the window cleaning when some witnesses are around at your premises, but due to the extra travelling involved, we would have to pass on the extra cost to you.
However, we would prefer to keep our price the same as it is currently and I imagine that you would too.
I am surprised to see that there is a hint of mistrust in your letter. I can assure you that I would not permit you to be charged for work that has not been carried out. The good name of my company is largely based on trust and goodwill.
So stick your job up your a*** .
No no, not that last line

I do agree with Windowwashers that your initial response seems far too strong. Sleep on it a day or two I suggest.
