They both interacted with the NPC but i got no vaild proof for that...
You have no proof that he used this for his own good, I get that they both interacted with the NPC but you don't know that he took something for an roleplay advantage, the user could have reported not being able to take items out, for DanKeK to confirm whether or not this is an issue for just that issue for the server he would have to try himself.
