If we're talking about odd celebrity encounters (!), here's one....A few years back, Mrs Lozzer and I were in Barcelona on a city break. We were on the rooftop of the Casa Mila, taking photos over the city. Out of the corner of her eye, Mrs L spotted a certain British politician reading a book.
"Look, there's Michael Portillo!" she said...
Mrs Lozzer knows no other volume setting than "loud"... anyway, he definitely heard her because he took off like a gazelle, pushing through the crowds and away down the stairs.
We both thought it very odd behaviour, until we arrived home and read the UK papers. Apparently, reports of certain 'indiscretions' from his younger days had surfaced in the press and he had gone AWOL. Evidently my SLR and zoom lens may have given him the impression that I was a member of the British paparazzi.
