Yes u made the right decision for sure. Since better for her like this.
I just imagine what if I am there in that store and she came in to ask advice.
But of course I cant blame also the guys since they are not responsible what happened with the poor guy who died and who knows what is they financial situation. Maybe they have loans maybe they just earn a small amount like what is just enough for they living.
So hard to judge because we dont know all the details.
But this is sad if those guys in the store they have a good income than they actually robbed her.
So I just made my opinion what if I am the one who is there at the store.
In your situation I agree 100%. Better to stay silent sometimes and just let everything as it is.
