While on these forums I of course expect everyone to be polite, I have no such expectation in the game and actually enjoy the variety of responses we get from NPCs

I do hope we get some additional snappy comebacks to some of the sarkier NPCs though. I've no interest in being violent to people who are a bit rude, but sometimes I'd like my character at least to be able to say something to take them down a peg. But not Barcus. Barcus is great just as he is.
