I mean, a lot of it is just people who started using chatgpt to do some simple and boring task (writing an email, CV, or summarizing an article) and started thinking that it's the best thing since sliced bread.
I would know that since I'm a university student. I know the limitations of current AI stuff so I can cautiously use it for certain tasks and don't trust the output to be correct. Meanwhile, my friend thought that he was making chatgpt better at answering his multiple choice economics quiz by telling it which of the answers it gave was wrong...
I don't remember actually doing tips as a percentage back when I lived in Latvia, it was usually that you took the bills and left any coins, maybe added some on top if there weren't many.
So probably 10% at most but still basically what I made per hour as a warehouse worker
