Whirly has spelled it out for us all. Whilst everyone in this thread is seemingly perfect and wouldn't ever get caught out with wx not as forecast. I know no one here would ever even think of money when looking at a diversion, because we're all perfect. Experience however has shown that other people do, and in a situation where there is a reasonable chance of a highworkload - removing one potential worry is a good thing.
I for one think Charles Strassor should be applauded for his efforts getting this implemented - and to be blunt am gobsmacked that anyone else can think differently.
Also, incase anyone wasn't aware, the scheme was set up to cover all genuine emergancy and precautionary diversions. Not just due to the weather.
Also agree with Genghis... buying lunch or sticking something in their charity box wouldn't do any harm.
