I don't know if some of you are aware but a very common tactic used by grand theft auto offenders is to use a girl as bait (damsel in distress scenario) to make someone stop the car and give them enough time to come out of some bushes or wherever their hiding and hijacknig it.
In that situation I would have ignored as if I had kids, their safety would be more important, not to mention the fact that she's flashing cash seems suspicious as most people if they saw someone in distress and were even paid to help them would.
