Dancer tipouts

I know this has been brought up many times, but I can't seem to find something up-to-date using google. I want to get a general consensus on tipout etiquette for dancers. I have been to clubs in Ohio, Maine, Florida, and California many times over a 30 year period, though probably not as often as some of you lol. I hit the clubs hard in 2017-2019 and again in 2021-present. This is what I think I have seen:

Dancers pay either a flat rate tipout, or tip various staff directly. I have seen clubs as cheap as $20 tipout, up to $100 or more to work that day.

Or

Tips to DJ, Floor Guy/bouncer, house mom, and ?

I have read that tips from a dancer in total should not exceed 20% though some club management are predatory and try to get more. Some clubs also I have heard of bouncers asking the girls to get their tip and then also ask the girl for 10%.

Also a girl that makes no money shouldn't be tipping, because tipping is always optional. Now if a place is charging them rent, that is different..Rent always has to be paid, money made or not...

So I may be wrong or right, but I would like to hear what you know about tipout etiquette around the USA, and even the world...Maybe I'll write a comprehensive article with my findings...

Thanks!
