So I for some reason i am standing here and wondering, I wonder what kind of logic would npcs have when you go buying weapons in the shops.

*player walks in*

NPC: Hello fine customer, we have a wonderful selection of deadly weapons today...feel free to look around.

*player eyes up insanely priced item*

NPC: Ohhh I see you are eyeing up one of our finest weapons, would you be interested in it? You don’t look at all suspicious and I don’t question how you have that much money...

*player buys weapon*

NPC: Enjoy your purchase and have a wonderful day! (Watches player leave and kill others close by with said weapon)
