Are the fees charged by the hotels at motorway services a threat to safety? If i'm driving and i feel tired, should i be able to drop in at one of them and stay free of charge on the grounds of safety?
Battersea has - in my experience - a very good record of being reasonable in such cases but at the same time, it's a business!
If you're going to go flying then you need to take responsibility - if you need to land then you land and worry about the money and the paperwork later.
There is already an agreement in place whereby airfields waive charges for genuine diversions - i don't know if Battersea is a participator in the scheme - i'm sure someone will tell us.
