It was only when I climbed aboard the bus that I realised that I had forgotten to check whether I had change for my fare. I explained this to the super-friendly driver as I rooted around in my purse for three fifty-pence pieces.

I put my papers down to the left of the money slot and they disappeared down the document chute.

“I need those back urgently!” I shrieked at the driver.

“That’s fine”, he said. “You take everything from out of there. I have no concerns about data protection.”
