I didn't say not smiling makes you an asshole, I'm making two separate points. The first was that expecting people to be generally courteous to other people, whether they're explicitly paid to or not, is something we should expect from everyone. It's called just being a human being. And again, everyone's allowed to have bad moods now and then. But in general, if you go through life with a scowl on your face and approach things from a standpoint of "I'm not being paid for this so I don't care, I'm not doing 'unpaid emotional labor,'" you're just kind of a jerk. That's the context of the last couple comments in this thread so it's important to keep the "I'm not being paid to smile so I'm not going to smile because that's labor" thing in mind.
The second point, which is related but I think still separate, is that I wish just being an asshole was enough to get fired. I sort of had it in my head but didn't really articulate that I was thinking of being an asshole as a more extreme version of what we're talking about, what I refer to above as just being kind of a jerk. Maybe on a scale of 1-10 being a jerk is a 3 but being an asshole is a 7 or 8.
You keep confusing being polite (something rightfully expected from an employee) with being fake and with real emotional labor.
This are 3 different things.
I don’t want a bus driver to fake cheerfulness. He’s there to get me from a to b, not to pretend to be my friend.
