Ghazzawiyya at King's Cross Station

I was stopped by a volunteer from the British Association for Cancer Research at King's Cross Station in London. She was explaining to me about the organization and she suddenly asked "where are you from?" For the mere sake of it, I said "Palestine." And, to the mere shock of it, she said "where is that?" The only answer that came to my mind was "it is under Israel." She got really confused and perplexed and suddenly said, "oh, anyway, I was just asking because you look Moroccon."
