There might be no such thing as a free lunch, but there may well be such a thing as a free falafel. I say that only because when I would get chatting to falafel stall-holders the subject would invariably turn to what I was up to in Israel, and the conversation would go something like this.
"Where do you come from, then? England, America?" the stall-holder would say as he took my order.
"South Africa - but I live in France," I would reply.
"And why have you come to Israel. Tell me, you are Jewish?" he would say as he began to prepare my falafel.
