Yeah I'm not really starkly in favour of a removal or anything, just pitching that as my opinion :)

That said, I think it's super possible to provide good service to people without honorifics! Making people feel respected is more than just saying a specific word a bunch of times, like maybe you're getting a positive result out of customers just because saying those honorifics put you into the frame of mind of being nice to them and taking them seriously.

IMO it's entirely possible to talk super fancy with a dozen "sir"s or whatever and be intensely rude (look up British MPs insulting each other as a potential example). Conversely I think it's possible to be extremely hospitable with rustic, informal language. Singular particles are not really the end of language, it's the greater action and meaning that matter way more.
