Probably not totally relevant, but a several years ago I was out for one of my best friend's very low-key bachelor party (just a few friends/family members bar-hopping, no strip clubs). We went to a bar that was recommended by one of us and the dude who greeted us was so insanely charismatic that I assumed he was someone my buddy knew and was this later joiner to the party or something. I asked my friend, "Do you know this guy?" and, you kinda have to know his humour, but he replied, "No, he's an NPC." He was not insulting the guy (in fact I think he may have even said "non-playable character" in full) just saying, "Nope, not with us," and ya... I laughed... like, really hard. Needed recovery time.
I don't know the point I'm trying to make.
