Used to work at a gun range/gun store. Guy walks into our empty store with a Mosin in his hands, not cased, and across his chest walking forward in a straight line towards the counter. All three of us simultaneously without hesitation drew our guns pointed downward, ready to raise and fire and told him to hold up his hands and drop the gun. He did so, and realized his mistake in bringing a gun in that wasn't cased or holstered. Turns out he was just a newbie looking to sell his grandpa's gun. We explained to him the importance of adhering to the signs on the door and entrance, and why it was important. He was obviously embarrassed.
You've gotta be ready. Real/attempted robberies of gun stores happen more often than you'd think. Their success or failure depends upon the attentiveness and implementation of policies by the employees to shut that **** down quick.
