That happened to me.
I was assisting an elder gent whom had just accidentally reversed onto footpath taking out posts and fixed benches.
Lucky he didn't hit anyone.
There was a young guy that was asking him if he was ok and I was trying to help the man out of the car.
The man reached for his wallet on the seat and we realised the young guy had taken off with it.
Very low.
After police and tow truck had been I called a taxi and prepaid it as he didn't have any money.
few years back hubby and were doing the woolies shopping and a very elderly lady went head first into the shelves droped her bag and tins were everywere
we were helping her up and i went to pick up her bag and she grabed hold of it and pulled it of me 
plucky old lady that
had her wits about her we have a laugh about it sometimes but its also sad that nowdays you just cant trust anyone
even if they seem to be helping you
