Problematically, the comedy switch in my brain always favors funny over appropriate, and the edit filter was never installed, so I didn't hesitate to say 'ooh, I'll have those,' in a bad comedy accent, pick up his biscuits and put them on my side of the barrier.
It wasn't champagne comedy, it's true. I was just looking for a little light relief in a crazy, mixed-up world, but I picked the wrong patsy. The businessman didn't appreciate my subtle comedic satire on supermarket mores. He snatched his Tim Tams back angrily and placed them firmly on his side of the barrier. For the next five minutes there was a terribly awkward silence.
He'll probably turn out to be the husband of some mother at pre-school, and I'll meet him at a working bee, and we'll always have a terrible, unspoken, secret past.
