All,
Thanks for these replies. Just to be clear, any fuel purchased is handled as an entirely separate transaction (Air BP, I recall) and does not form part of the airport's invoice.
Despite the very useful replies on Development charges and alternative taxy arrangements etc. the fact remains that on first telephone contact the clear message is that the bill will be £45 with no alternative. I for one will not visit under such circumstances and would urge others to do likewise.
That said, it would be a real shame to see the demise of GA at Norwich for want of a simple matter of 'putting the customer first'. But that requires a business ethic of treating folks as valued customers, not as two-legged cash-cows to be fleeced at every opportunity.
Mike
