Apparently this guy did not know about them:
It was then that the clerk, Sergio Morales, realized something wasn’t quite right.
“He comes around, cocks the gun,” said Morales. “I hear plastic.”
Realizing it probably wasn’t a real gun, Morales reached under the counter, pulled out a baseball bat and whacked the crook in the head.
The suspect quickly realized things weren’t going his way and ran out of the store.
Stupid criminals and puppies make me smile.
