Please understand I'm not telling "Florida" or you or anyone else what to do, or how to react, I'm merely stating what
I agree that there is no "simple robbery" and one must realize that someone pointing a gun at someone else is one of the most aggressive gestures known to man. It is lethal and it is not something to take lightly or think is no big deal.
HOWEVER, I must reiterate (again) that drawing against an already drawn and pointed gun is a very serious and equally life-threatening thing.
Florida, I challenge you to have a friend simply point his finger at you and you, with a dummy gun or your finger, try to draw and "shoot" before he can even say "bang" because that's about how much effort it will take for a bad guy to shoot you.
I would only draw against a drawn gun if a) they were trying to move me somewhere else, b) they had already showed they were likely to kill me anyway (in your situation, had they killed other clerks they had robbed), c) if I saw an opportunity wherein they were distracted and not paying attention to me (ETA: You could create such a distraction by dropping the money on the floor, knocking over a rack, etc) or d) I gave them what they asked for and they were still there indicating to me that they intended to stick around and kill me. There might be a few more variables that would induce me to go for it but IF I choose to draw against an already drawn and aimed gun I would be doing so with the knowledge that I'm more than likely going to take a bullet or at least get skimmed by a bullet. I might get lucky but the math is not on my side.
Just my opinion, and we're all entitled to our own. :wave:
This is why avoidance and awareness are far more paramount. If you can see someone in the parking lot putting on a mask or approaching with a mask on (especially in summer months) THAT is the time to act by at least seeking cover because once they get inside, if they have guns drawn, your chances of a successful gun fight go WAAAY down.
Again, not impossible, but it's not good and your chances of survival go even further down if you haven't trained for this.
