Due to a combination of absent mindedness, incompetence, ineptitude and the forces of darkness conspiring against me, I had to go to the supermarket
three times today.
As Lady Bracknell might have said, 'once is misfortune, twice is carelessness, but three times is a real embuggerance'.
Anyway, on the final visit I found myself in the checkout queue behind
John Benjamin the jewellery expert from the Antiques Roadshow.
Whilst I recognised him I think I can say, with a fair degree of confidence, that he didn't recognise me.
