Respect

..or not.
Ok, so leave your car in our parking space and take off in your whopping motor yacht, only to return to find a wheel clamp on it.
Then you have to walk all the way to the marina office to find someone to remove if.....if there is anyone still there when you get back and you need it.
Whoever you are, a little respect and you could have avoided all the hassle.
A few hours later the owner turned up, loaded his bags in the car and started on a rant when he saw the wheel clamp.
He took off on the back of  motorcycle belonging to a guest or crew, straight to the marina hq. Twenty minutes later the clamp was removed, and he drove off with a much younger woman. 
Of course.
I hope he remembers to use his own assigned car space next time.
