The problem with the whole "it's not a personal item that's marked" kind of argument is that they KNEW it belonged to one of the others running the race. I don't give a rat's patootie about other circumstances even. Had they not known that it was a fellow racers money, I MIGHT be able to see the rationale, or had they just randomly found money on the street, I could totally see , but by my very nature, I can't under the circumstances.
Now I shall stop beating this dead horse. (I thought there was a dead horse emoticon).
