Hey, lets keep this thing going....
I do a lot of work on the local Air Force Base, so in addition to people being altogether too "precise" when talking bout things they don't understand (our magic boxes that make things work...) they live in a world of acronyms, and assume that you do to.....
Double fun (frustrating) is when you finally figure out the acronym they are using is both incorrect use of leading letters, but also describing the incorrect thing! But it's their world, so you have to roll with it.
