Well, if possible that u can add an NPC rate when u aims at them to rob the store i want to suggest it
When u first aimed at him it should say that he's confused, Seconds later after uu aimed at him it should say that he's scared.
When u not aim at him anymore it should say '.... might draw a gun', seconds after u not aiming at him the npc starts to fight back and shoots u just like the safe guard in bank attacks whoever is trying to get closee, Thats all
