Such a debate over £1, which you can avoid if it makes you lose so much sleep... safely (long stay car park) and not so safely..? You spend £100's or £1000's on a holiday and moan about spending £1, yet wouldn't think twice about spending more than £1 on alcohol to piss down to toilet, cigarettes to slowly kill yourself, betting to more than likely lose..etc ... ill grab my coat now, i give up on some people...
While it is an additional income for the airport, i also believe that they donate a day or 2 per month to a charity..
