That kind of thing has been going on for a while now...
I saw a ramper get written up because he didn't challenge an FAA guy on the ramp... but he was hooked up to us on tug and headset. I noticed a guy standing about 20 feet behind him just looking at him. The ramper couldn't see the guy since he was facing us on the tug. I say to the captain... "Who's that guy over there?" The CA looks up and says... "I don't know..." By this time the ramper had gotten of the tug and walked over to unhook the GPS and then return to the tug while still hooked up on headset.
The guy behind him immediately walked up behind him and got his attention... the rampers mic was hot and we heard the whole thing about how he was with the FAA and to not go anywhere after this pushback because he'll need to speak to him and his supervisor since he didn't challenge him.
The Captain was pissed... he got on OPS freq. and told the ramper's side of the story to our OPS folks... that the FAA guy was behind the ramper... and the only time the ramper could have seen him was when he got off the tug to unhook the GPS and yet was still hooked up to our aircraft and essentially in control of our aircraft just prior to push.
It would be different if the FAA guy just casually walked by him while the ramper was on his way to another gate... but in this case... it was a bit over the top.
Regardless... we let ops know that we had noticed the guy and that we were about to question him but he came up behind the ramper before we could do anything.
The CA really went to bat for this guy... we delayed our push 5 minutes while the captain spoke with the guys supervisor on the headsets with the FAA guy still standing there. He gave him his name, EE# and Cell# and said that he'd support the ramper 100% and that the FAA guy was wrong in doing what he was trying to do while the ramper was in the middle of performing an essential safety function...
After the pushback checklist and just prior to the Taxi check... the Captain turns to me and say... "God I hate the FAA!"
Anyway... that was last year.
The FAA... they're here to help...
