A Las Vegas vape store owner was ready when an armed robber jumps over the counter ... and it was all caught on video.
The attempted robbery occurred in the middle of the day Wednesday.
Video shows the 22year old store owner Johnny Nguyen behind the counter as he’s approached by two people wearing ski masks.
Nguyen asked them to leave, but one grabbed the tip jar and another jumped over the counter.
That’s when Nguyen whipped out a 3-inch blade from his pocket and stabbed the dude like he was playing a game of whack-a-mole.
