Today I grassed, would you ever?

I've done the same thing. Motor bike Policeman stopped to have a word with a driver on the approach to Albert Bridge and then rode on, I was well behind. Caught up and passed the car and the driver's on the phone, so I caught the Policeman halfway across the bridge. "Did you just talk to the guy using a cell phone back there in the green Jaguar?" I said. "Yes, I told him to put it away." Says he.
"Well he's back on the phone now."
"Oh is he?" - he then puts on his lights, does a U-turn and goes back up the road. I could just see the Jag driver's face, it was an absolute picture.

nice.
