Thats a great story!
That’s terrible that someone took one of this woman’s shoes (apparently? that’s what it sounds like), but how great that you and your wife were able to help her keep going. What a great story - thanks for sharing!
Dude, your wife is too cool! Great story!
The only thing that surprised me was that you didn’t bother to offer her a flat coke … 
I don’t think outside assistance is an issue in this case, common sense has to prevail at some point. That was a very nice thing your wife did, she made someone else’s day (more like year).
