I remember back in the late 80's getting my first passport was a friggin nightmare. I went to the World Trade Centre first thing in the morning and waitied for 4 hours for my number to be called. Once I got to an officer, he looked at all my credentials and found that everything was in order except that my friend who was a CPA, just signed that back of the passport photo and did not write, "This is (my name)" above his signature.
The officer told me that the photo was invalid and would not accept it. I had to go all the way back to Burwood, get him to write "This is (My name)" above his signature and returned to the World Trade Centre to wait another 3 hours before my number was called!.
I have to admit though that all my renewals since have been a piece of cake.
