There are different scenarios that have panned out in real life or are applicable in these scenarios.
1.) Give them the money cuz it's not worth being a hero UNLESS you are confident you can take them on. OR if you're just having a bad day and you don't give care about your life anymore then go Michael Douglas style like in "Falling Down."
2.) Throw the money and run.
3.) Do it mob style. Give them the money then remember their faces and get em afterwards. Vigilante style...bats to the ribs are best. It's like what they do in cop stations...beat you up with sacks of oranges so it gives you internal bleeding and doesn't show any cuts or lacerations.
4.) An acquaintance of mine knocked out several of his would be attackers, BUT got stabbed in the lungs in the process. Not before taking them all out though...
Depends on the situation if they're armed you'd be prudent to talk your way out of it unless you know they're going to hurt or kill you anyways then. Bottomline knowing martial arts doesn't give you carte blanche to hurt people unless it's in self defense of course. In that case swing away...
Marcus Aurelius: Tell me again, Maximus, why are we here?
Maximus: For the glory of the Empire, sire.
Baked, not fried... the healthy choice.
