I never owned a Stripperbar but many years back in the day as a sidebiz I opened together with a Friend a nice Bar, right on the Mainstreet, full from 11PM till the Wee hours.
we did not depend on the incomeof the bar for a living as we both already had our steady good income, it was a Fun Idea to have a Bar as We like to see a Bar to be.
been Fun to learn about all the lil sidekicks and to know within a few weeks all the uniformed and not uniformed Buggers existing in such lil Area.
check out the Area where You wanna open such Nightclub firstly, get to know some "People" in that Area firstly BEFORE You even talk about to open such Biz, be for yourself clear what You 'think' about Drugs in Your Biz, 'cause they will come in anyways and it is YOU who has to handle them.
register only 1 Firearm in Your Name to have a "Card" to show, put it at home in the Safedeposit box and get a collection of the not registered Handy ones, the "Disposible" ones, sooner or later they are needed.
Your OP sounds like You are new to that Kind of Biz,
don't start such unless You are since many long Years very familiar with the specific Area where you wanna start such Biz.
good luck
Mike
