I was working in Croydon last week.
One day I had a sudden craving for chocolate, so I went into a newsagent in my lunch break to get that chocolate fix. While I was waiting to pay, two young women in front of me were having a food conversation with the shopkeeper. He shared an Indian recipe with them, potato being the main ingredient. One of the women pulled a face and said: “I don’t like potatoes, but I do like chips.”
At this point, dear reader, you are more than welcome to take a few moments to ponder on the profundity of that statement.

These are not potatoes. Just wanted to make that clear.
When I reached the counter, the shopkeeper was staring in the middle distance, repeating what the woman had said, as if in a trance. I furrowed my brow in solidarity. He snapped out of the trance and quickly followed with “And I suppose she thinks potatoes grow on trees.” I laughed so loud and so suddenly that he almost jumped back into the cigarette shelf behind him.
Classic.
