He had put on weight. Bulked out.
He came to the counter with a book and asked me how I was.
I told him I was fine.
He complained of tiredness.
Do you mind, he asked, if I pay you with change.

He emptied out the pockets of his jacket onto the counter, pilling up a mountain of silver, collecting the coins into neat one pound piles until he had nineteen pounds.
Enough for a penny change.
And an instant diet achieved.
