Clacton causes plenty of problems - at both ends. The upper-lower wind transition catches a lot of people out, then the hump in the middle of the pitch.
Toughest approach I ever saw though was an ex-BA captain on his first Cub solo, who while he had no problem with the plane, was obstructed by several of the local gentlemen who decided to splay their shell-suited persons across the touchdown point every time he turned short final.
Sure they have something at Baghdad Intl for this kind of eventuality....
