The Blood Center of Central Texas "Elevator"

The usual motif of ads that ask us to give blood, donate to charity, devote time to a worthy cause, etc.: You’re a good person, so you’ll want to do this good thing. The motif of a new campaign for the Blood Center of Central Texas (via Door Number 3 of Austin, Texas): You’re sometimes a bad person, so you’d better “redeem yourself” by doing this good thing. Depending on your taste in such matters, this is either (a) a refreshing change from the well-worn approach or (b) a wrong-headed deviation from the tried and true.
