I had an amazing thing happen today!
I had to go to the Citizen Services at the US embassy today to get pages added to my passport and get a document notorized.
You have to make an appointment from http://bangkok.usembassy.gov/service.html to get pages added, no appointment was needed to get the document notarized.
My appointment was at 10:30. Despite the vagaries of Thai transport, I was exactly on time. After having the woman check all of the paperwork and me paying for the services, I turned in my paperwork.
At ~10:50 I'm called to the window, do the notary thing and she gives me my passport with the extra pages. ~15 minutes or so from start to finish.
I complimented the lady on the speed of the service and she said that never come early as the place is a madhouse, the best time to make an appointment is after 10 or better yet between 1-2 after lunch.
