I remember this moment vividly. It happened in Egypt. A man approached me with a camel, trying to sell me something. I told him I wasn't interested and had no money, but he didn't seem to believe me. Suddenly, he plopped his turban on my head and said I should take a picture. After I took the photo, he demanded payment. I showed him my empty pockets, and he quickly snatched back his turban and disappeared. The worst part was the turban’s awful smell; I could still smell it an hour later. I had to wash my head as soon as I got back to my place.
