Great dialogue....
I too would take cover and draw my sidearm.
Obviously if the clerk is being shot at or is at gun point the situation has become volitile.
This BG is not stupid I assume he knows I am there. Cover and move to not be a victim as well.
- call 911 for back up on my cell.
(Given he has stated he does not want to harm the clerk)
- I give clear directives to drop the gun and lay on the floor.
(if this does not work, attempt to defuse the BG while behind cover)
-By this time L/E has arrived and I can begin to back out, if possible.
Then, (exhale)
- go home (after debrief)
- change underwear
- drink beers
