I can tell you my own version that doesn't involve anything luxurious or fancy at all.
You wake up at the crack of dawn before even sunlight is a thing, you are basically waking up at a late night hour instead of early morning hour (usually around 04:45 or 05:00 but depending on shit it could become 06:00 so that's better) then you work no matter how sick you are, I had high fever one day and went to ER before work and get some shots done and had vial plucked to me for vitamins and medicine etc and went to work anyway afterwards to work on 13 hour shift.
You get yelled by your boss for even standing still, not even a joke, you have to be in constant movement and constantly smiling so forth so if you are just standing there with your resting face (not even upset or sad face, just your regular face, not like we all smile on default) you get yelled at. Glad I am not in that world anymore.
My experience was nowhere as bad as yours, on the contrary, now after something like 10 years since i quit i remember it as fun part of my life
My shifts were usually 12 hours long(7am-7pm day shift or 7 pm-7 am night shift), but we had schedule where you would work 2 days, and then next 2 would be free. And we would often exchange shifts so we could combine more free days when needed. So for me that was one of the better sides of the work, as i was often able to take small trips.
I don't know where you worked, but here in Europe workers are decently protected. While working for one casino i had injury (happened outside work) that forced me to take sick leave for almost 4 weeks, and i got full salary during that period, as company appreciated good workers. Of course, i worked sick sometimes, but never when I am seriously ill. That is common thing i think at most workplaces, you won't take sick leave if you have cold.
Another perk was working with a bunch of hot girls, male/female ratio was awesome for a single guy like me
There were some bad sides, like watching people loosing everything they have, while loan sharks standing next to them and "giving" them more money, getting them into more trouble, meeting bunch of shady characters, and in one "unpleasant" situation i even had to go to court to testify. It is stressful too, as depending on the position you are dealing with a lot of money.
Money wise i was making an average salary for my country, but when you add tips it was quite decent for 14-16 working days per month. Sure, you work on weekends, holidays etc, every day was the same for me. So this job is not the best when you have wife/husband, kids etc.
I worked in that business for 6 years and I think it can be interesting and exciting work experience when you are younger( i was 20 when started) and even when was tougher I looked at it as a professional challenge. Later on i kinda got tired of all that, and wanted more relaxed and slower work atmosphere.
