Robber pulls knife on a cashier, doesn’t know the man in white has a gun

While waiting in line to check out at the grocery store, a man with a CCW permit became a hero and saved a cashier’s life in the next lane.

The man in black has supposedly dropped his own items off for checkout in the lane on the left before turning his attention to the cashier on the right.

He draws a knife, presses it to her side, and speaks softly into her ear. Not everyone can see what’s happening, but the man in white behind him sure does.

He quietly draws his firearm and orders the man to drop the knife.
