One of the things that really annoy me in my line of work is reading technical specification documents, real thick ones at that too and what's worse is that some of them are out of date but none of the technical support/sales staff would tell you that until you it out on your own.
My current ordeal is to go through a 300 page technical specification document (plus certification document) for a type of computer Kiosk used at the airports.
At least the abbreviation they used makes me giggle every time :)
