I have a friend who has a pawn shop. He built 2 cages one is empty the other has poisonous snakes in it. During working hours he leaves the snakes in full view. at closing he closes the blinds and rolls the occupied cage to the rear and the empty to the show room floor.he then reopens the blinds. works good most every one is scaired of snakes.At my old shop when I first moved in I walked around the area with a constriction snake around each arm every one thought I was crazy.snakes are easy to buy many years ago I caught and sold rattle snakes for the antivenom program the others I sold to local church groups for services. I always let every one see that I am always armed. one last thing I have a sign that read if you dont know the owner by first name keep out and smile you are on video..
