Right on Gertrude the Wombat!
Agree 300 %, it often escapes the GA community that airports/aerodromes operate as businesses. I've lost count of the times that I've been stood behind someone who has been asked for a £15 landing fee, only to reply "how much? I just wanted to land here, not buy the place!"
PS, I love all Beavers whether powered by a piston, turbine or two legs!
