Your elbow hurts!
As you walk down the street you wonder how you would have felt about yourself if you'd just left. Sure, you may have embarassed yourself and probably made the situation worse by interfering, but who wouldn't do that if they were in your shoes, you know? You'd have felt like garbage.

"Don't think I will, thank you very much," you say.
"Not my fault I dropped it." he says, coming closer to you. "Pay up right now."
This is very obviously a scam no self-respecting person would fall for. You have no patience for this.
You crack your knuckles and...
