The cafes' have more passing trade than pilot trade. I'm there most weekends, and the restaurants are always heaving. It's not going to affect the aviation trade - they don't need to pay for the parking meter do they!!
Shoreham has had it's NDB unservicable for months, the airport can't afford to fix it. The parking charges are not a sound revenue generator, they're the last effort to get some desperatly needed coin in before the parent company goes bust. The decisions are NOT sound business ones. Take it from someone who DOES know what they're talking about.
