Talk about bailiffs skylining. When I lived Dan Sowf I was a member of a popular St. Albans club that had a section of the upper Lea. A very prolific tiny river here with loads of chub,barbel and carp. (Even more popular nowadays I understand).
The old boy was so good a bailiff he was too blooming good.
One would creep up to the edge and get down below the skyline and start trotting a float down.
Despite having checked your ticket just about 3 or 4 times a week for ages he would insist on walking along the edge, fully skylining in his white mack to see it again.
I eventually got round it by walking into the centre of the field when I saw him waving my card. He would have to divert away from the edge to intercept me. He never caught on as to why.
This rings a bell, a lot of the old school bailiffs were like this, they'd literally get into the water just to show you their ID card
