I know it's not my place to say it, but you know me well enough to know I'm gunna' say it anyway. I would submit not even putting your shoes on until you have spoken with the stranded rider on the phone as an excellent prevention method.
So glad the
exist, but I hate to see threads where volunteers have to waste half a day looking for riders not willing to pass on a phone number, or having to scoop the same rider over and over, and people not compensating angles for their fuel, etc, etc.
It all just takes away from the meaning of the 'service' as if the gift of your time is now a mandatory service entitled to anyone that joins a forum. It's become a less sustainable model of charity, and more of a burden from what I have seen.
