As for the suggestion that he should carry a weapon? Are you sure that he would want to go through this process just to have the privilege of being able to use a firearm in self-defense on some "pig" who comes into the shop and tries to rob him? In the United States, the laws pertaining to licensure to carry a weapon differ from state to state, and are affected by Federal Law as well.

Mr. Schneider is in Cleveland, OH. These are quotes from the law concerning obtaining licensure to carry a firearm, and the requirements of the training course he'd probably have to go through.
[...]
He would not only have to meet very stringent requirements to even legally possess the weapon, but he would have to be entered in the police data base, so they could keep track of him. And, he would still be vunerable if the assailant were to disarm him, or have even stronger firepower on them...and the will to use it!

So, keeping in mind that he has been robbed three other times in the last two months already, perhaps the better option would be for Mr. Schneider to relocate his business elsewhere and/or hire licensed security personnel to guard the shop. If he continues to run an IBS at all.
