I want to preface this with the fact that this is not a personal attack.
"In that case I told the nice agent I will do that as soon as they get the new forms for replacement plates at the SOS."
Uhm, I left my Super Sekrit Decoder Ring at the house.
This forum drives me crazy in the impetuous, reckless uses of acronyms and abbreviations that are uncommon and not referenced within the posting by the poster.
By far, the most common usage of SOS is the Morse Code equivalent of the MAYDAY distress signal. I don't get the license plate connection here.
OK, we're on the Internet, so on the the next most common usage, which is used in Internet Chat Rooms, meaning Sibling Over Shoulder. The license plate thing doesn't seem to apply here, either.
I didn't see where the plate was dirty, so I don't think SOS Soap Pads were used for cleaning it.
Condoleezza Rice is the SOS (Secretary of State), but I don't get that connection, either.
After much (much too much) time I'm finally able to decipher the code to discover the intended information conveyed. That, unlike the vast majority of states, Michigan classifies its Department of Motor Vehicles (DMV, which is by far the most common acronym used in the US for the department that handles license plates) under the Secretary of State (SOS) Department of State banner. That, people who are from, and are familiar with, the state of Michigan would understand that SOS and DMV have the same meaning when talking about license plates. I can only assume that the Customs official was from Michigan, and that he completely understood the full meaning of the SOS as used here. (Then again, if he was from Michigan, he wouldn't have questioned the missing plate. So, I dunno.)
My point being, the use of acronyms and shorthand is fine, but what's the point unless everyone is on the same mental page as the author of the posting?
And with that, I give you my version of the opening line of Lincoln's Gettysburg Address, in SMS Messaging:
