All tips are supposed to be taxed. That being said, every single one of my friends that have worked jobs that are primary tip-based would mention that they would hide some amount of the cash tips. This was to avoid taxes, and for the most part my friends would claim most of their cash tips while mentioning that if they were having a bad week or day they might hide more. I have been in restaurant and other service jobs which I was paid normal rates due to being either technically BOH or otherwise not a tip expected job. So in those cases I wouldn't claim a random tip I would get since it was never more than $20. Also the servers didn't have to split anything with BOH since BOH was paid at least $6.50/hr back in 2003 (which was like a dollar or so more than state/national min wage) and the servers were something like $2/hr or so with tips being of course the main source. Though they would give some to those of us that bused their tables quickly on busy nights to get them ready for a new person/group.

But I think that tipping should be completely something that is to show that the worker was in your opinion just worth more than whatever they made the time you interacted with them. As the idea of a tip (IMO) is just that, a more personal sign of appreciation for their labour even if they are being paid like any other worker. And yes, I believe that holds true for stuff like strippers or any other currently legal sex worker (and same goes for prostitutes if made legal and officially taxed).

I am from NC, and not the most high income areas while not being in the lowest either. But $30/hr is almost twice what I make in my non-tip-based job (I am at a pay-cap of $19.48/hr). That sounds like shit I wouldn't start to see unless I climbed the latter a lot to get (and completely stop doing the actual stuff I am any good at). So I am guessing $30/hr where they are planning to open must be like getting less than $10/hr where I am when adjusting for living costs and all that. Otherwise it seems like a real strange hill to die on when it isn't like the people coming into the place won't still do it if the servers are just doing really well. Idk. I stand with the workers no matter what they do, but if they lose the $30/hr for tips-based and the people that come in do what so many do (which is just lord over the worker). Then it would be a real motherfucker.
