If some huge guy in a leather jacket who moves kind of mechanically buys a bunch of guns DON’T LET HIM HAVE THE AMMO!
Or if he asks for a pulse 40 watt rifle!
Over the years I’ve seen several weird things at gun stores. One guy wanted ammo for a .25 cal military rifle, it didn’t matter what kind, HE would make it work!
I took the clerk aside and told him not to sell this man anything, as he would end up hurting himself.
In another store, some man was looking for powder and ammo for a black power pistol he had purchased sever weeks before, He had no idea what he was looking for. He chose a smokeless powder and a bullet that was too big.
Again, I told the clerk to watch out, as this young man had no idea of what he was looking for.
I’ve seen others who had no idea what they were after.
