Yeah, I have, and it's totally understandable that it's stressful and can push you and you can get close to breaking. That doesn't mean you deserve higher pay for it... other people have to put up with coworkers who are shitty or annoying, jobs that are stressful and heartbreaking even without customers deliberately ragging on them, and lots of other shit that's emotionally trying. You still get paid on the value of your labor and how easy you are to replace... the high turnover rate is also largely in part because it's super easy to train any half-sober hillbilly off the street to replace you, and that's exactly what they do.
Value of labor is the only sensible and fair metric to pay someone off of, not something vague and unquantifiable like "emotional labor". So what about someone who's just a relentless optimist and has a good day dealing with people no matter how many Karens they encounter? You gonna pay them less? What about sociopaths who just aren't emotionally affected by what others think or say? You gonna pay the delicate sheltered woke who only made it a half day out of training $1000 for that half day because she was way more emotionally traumatized the first time someone called her "sir" just because of her neckbeard than a normal person was working for two weeks? Of course not because all of that sound ludicrous. But I guarantee you the moment there was a hint of give on the "pay for emotional labor" front, crybullies who are just a different variety of Karens themselves would be spraying WD-40 on that slippery slope.
That said managers need to be more present and need to be more forward about telling customers not to abuse the staff or taking over if it looks like the staff is having difficulty. That's the actual solution because then being capable of handling customers who are emotionally abusive or confrontational really does pay you more.
