Maybe I just don't get it, but why would the girl have to use "strange behavior" or use code words or any such, to ask for help? It isn't likely that if she had been abducted or was otherwise in danger, the male she was with would have allowed her to use his phone to call for help. Likewise, once tow truck guy arrived, and was physically there with her, if she were in danger, it would have made a lot more sense to just yell "help me", rather than to try to play charades and hope her needs were figured out.
