I ended up having a custom rubber stamp made with my signature and the phrase: "Goodbye and good luck!" above it. Whenever a person would bring a card by, I would rubber stamp it, even if it was a birthday or congratulations card. If they weren't leaving, I would just cross out the phrase above my sig.

So you're the bastard that didn't have the decency to actually sign my card... heh j/k Where I work if we did that there would be a new card just about every other day. The place is going downhill and new people are hired because no one wants to stick around. I've been there a little over 3 months and have been their longer then at least 70% of the staff.
