> Gordons windows
You just tried to destruct my argument and then in the PS tell me I'm spot on.
Anyway -
In your car wash analogy you take your car to the powered car wash which gives every car exactly the same amount of time and detergent and power whether it is dirty or not.
Window cleaning is like a hand car wash and that is the similarity - I said "if
you wash your car every week it is different to monthly etc" not "if you take your car to a car wash".
When you've got a set up (in fairytale land) where the custy brings his windows to an automatic window wash then you might have an argument that stands up. Until then think it through.
But I agree with your PS!
