I had a funny thing happen to me at Miami airport, a few years ago.I was arriving from overseas and went through immigration. The official looked at my passport, looked at me, looked at my passport again and said: "If I were you, I would get a new passport, this picture of you is awful". My passport was about 5 years old, and I hated the picture as well. It had been taken by an instant camera in a camera shop. Well, I took this to heart and went to a photographer and had my picture taken and renewed my passport. I now look like myself in the photo and haven't had any comments from an official since. I didn't know that I was that vain.
