Slavoj Zizek

For the second time in two months, while shopping at Hyde Park Produce, I have seen someone who looks exactly like Slavoj Zizek with a young woman.  He walks around very quickly, pointing at various pieces of food, barking their names in a thick eastern European accent while the woman either consents to or denies his suggestion to buy the item.  But the more important point is: why is Slavoj Zizek, or an astounding lookalike, frequenting produce shops in the middle of Hyde Park?
