I don't think there's a real difference. Thinking a job is "mundane" IMO is mostly a case of not working that job. Many "mundane" jobs have depth and rewards, even if not in every instance.
I've heard people express that they liked working in retail. By extension somebody must have enjoyed being a bank teller. After all, why not? You get to talk to a lot of people, and every time you solve some problem or answer a question and get thanked for it you get a little rush of endorphins.
Many jobs that suck only suck due to external factors like having a terrible boss or terrible customers, or having to enforce some terrible policy.
This sounds like a strawman tbh, I have worked retail for years and I do not know a single person enjoying retail work. Especially not cashiers. I can understand what you are on about, but do you think this is the majority of people? The issue is being able to support yourself which these mundane jobs hardly are able to.
Personally I want these mundane things automated because I don't want to interact with people. I appreciate art though and I want to support human art. I appreciate everything from ancient architecture and stone cutting to renaissance paintings to basement drawings of amateurs. Art used to have character and now its all the same AI slop. Video games will become unplayable for me in the near future. Advertisements will be fully AI slop. Sure there are still artists out there, but they get overshadowed by AI slop.
I mean, retail has many different instances of it. Yes, I can imagine working in a busy supermarket owned by a giant like Walmart would be unpleasant.
But imagine working in a nice cafe in a quiet small town, or a business that's not too frantically paced, like a clothing store. Add some perks like not always doing the same job and a decent boss, and it shouldn't be too bad. Most any job can be drastically improved by decreasing the workload, cutting hours and adding some variety. I don't think being a cashier is inherently miserable. It's just the way we structure things most of the time makes it suck.
Just like you think a human touch makes art special, a human touch can make a mundane job special. A human serving coffee instead of a machine can tell you about what different options are available, recommend things, offer adjustments a machine might not, chat about stuff while it's brewing... You may end up patronizing a particular cafe because you like the person at the counter.
