In fact, I don't think he's ever rolled for NPC reactions either, nor has he ever asked me for a Charisma check outside of a Non-Weapon Proficiency, so I don't really know if my bonuses to NPC reactions from both high (or low) Charisma/Comeliness are functioning. That's not the say I think he ignores them, but he uses judgment calls and roleplay instead of dice rolls with regards to social interaction with NPC's.
Which is fine, I think lots of DM's do that. Randomly rolling to see if NPC #772 likes you and keeping track of individual NPC attitudes would be tedious, plus it's very possible (especially in 2e, where many Kits grant large bonuses for dealing with particular types of NPC's) that rolling can be a pointless exercise. I have one character who has been around so long that they've drawn the Throne card from the Deck of Many Things on three separate occasions, so they have an 18 Charisma and an additional +10 loyalty adjustment and reaction bonus on top of the normal bonus provided by that ability score (as per the rules of the card)- at this point, if one was slavishly following the rules, it would be rare for any NPC ever to have a negative attitude towards said character.
