Matt, looking at the bright side of it, you now know the true nature of the character (or more aptly lack thereof) of the man you tried to help out. One person at least that will have to follow the rules/regs to the letter next time he comes asking for something.

As the old saying goes, "it only takes one aw-sh*t to wipe out a whole bunch of attaboys". You seem like you got a good head on your shoulders; I'm certain your supervisor won't even remember this even happened in a week. Remember this saying too: "it's better to HEAR about something than READ about it". I.e., on your eval.
Keep your chin up and your head down!
