omg... do you have any idea how incapacitating pepper spray or ammonia is? It will IMMEDIATELY blind you (temporarily) and make it impossible to breathe. You WILL NOT be thinking about money at that point.

this is true if you get him in the eyes. what happens when a robber with a gun sees your dad pointing something at him? the robber draws his own gun and kills your dad.

what happens if your dad misses his eyes? On clothes or skin will leave plenty of time for robber to get to your dad and take him out.
