…which for some reason is a surefire way of making my visitor numbers swell enough to fill at least three double deckers, this photo reveals a bit of a design flaw with fenced-in bus lanes.

What you can see is a huge queue of buses, stretching from the Tesco in Seven Sisters and finishing - I guess - somewhere in Tottenham.

Just before I arrived on the scene, a police car had stopped outside the supermarket so the two rozzers inside it could go and arrest a pair of shoplifters. Whilst they were busy doing so, a massive queue of buses formed. As I arrived a policeman was removing the car and easing the huge jam he had caused.

As I left, two coppers and two shoplifters were shivering in the cold, waiting for someone to come back and give them a lift.

No-one a winner, really. Except me: I had no trouble at all catching a bus home.
