Newbie Looking For Advice

It depends on the club. i take into the club the absolute LEAST that I need... I slip my big bills into my phone case along with a club coupon or card (if needed.) soft shorts and shirt. sandals or flip flops. one dollar bills in one pocket. others in another. one cheap copy car key.

and keep a low profile. drive a cheap car. no bling. Maybe you don't even need your phone. And you don't need a wallet. Maybe the club has limes or mints at the bar for your breath issues.

keep it simple. the ABSOLUTE MINIMUM you NEED.
The lock box is a good idea.

I put next to no thought into any of the things you're concerned with.

Cash/Card wise, I bring my normal wallet. I usually hit the ATM prior and grab some extra 20's and 100's. I've got smaller bills, 1/5/10's that I'll keep in my front pocket for easy access to tip with. It gets replenished when I buy drinks.

I wear what I'm wearing, meaning I don't specifically dress for the club. I live in south Florida and mostly club in the afternoon, so most often that's some kind of golf shorts and a polo or board shorts and t-shirt along with tennis shoes or more often than not flip flops. But occasionally I'll have dress/suit pants and a shirt and real shoes. Every once in a while I'll wear jeans and maybe a sweatshirt, if I happen to go to a club when it's a bit chilly out. That stuff is almost always just when I'm traveling though.

I brush and floss regularly, I suppose if I know I'm going to the club I will brush just before leaving. I keep a small mouthwash bottle in the truck, I'll usually use it in the lot. I tend grab one and toss it in the rental car when I'm traveling too, but that's more for the office than the club.

I don't do anything special with my keys. They're in my pocket like they are every other time I leave the house. When getting dances, if there is someplace to set them I will often remove my phone and keys from my pockets and take my sunglasses off my head/neck. I've developed a self pat-down habit every time I stand up, I always inventory for phone/keys/wallet/glasses when I stand up. Again, it's not really a strip club thing, it's just a habit I've picked up.

As others have said, I don't take too much consideration into most of this stuff. For dress, I try to dress comfortable for the area I'm in.

I do carry a small pack of Listerine Breath strips in my back pocket to be fresh when I go back for a private dance. I have one dancer that has the abilities of a blood hound and she appreciates this. She's even asked me for one when she wasn't feeling fresh.

I take my driver's license and my drink card (Desires) and wrap 6 or 7 hundred around it. If it is winter, it goes in the pouch of my hoodie. Summer left front pocket of shorts. Phone, keys and vape (so I can get high in the club) go into pouch or right front pocket.
Winter - hoodie, soft pants. Summer shorts and t-shirt. Commando always except when I wear a suit to work. Footnote: 99% of the time my real-life dress mirrors strip club dress. I simply look like some homeless guy most of the time except when I appear in court. In my office summer attire is shorts and a wife-beater. I do a possession check in the club and irl every time I move from one position to another because I lose shit pretty much weekly.

I never carry ID or credit cards or anything else with my name on it into the club. If they absolutely require an ID I retrieve it from my vehicle and bring it in. And then I take it right back and stow it safely back in vehicle. I refuse to let any club scan my ID. It's very rare that I run into that scenario.
For keys all I ever carry is a key FOB for the car on a thin but strong chain hanging in my pocket and secured to a belt loop.
My pants whether long or short always have multiple zipped pockets. Big bills in rt rear zipped pocket in a very small binder paper clamp.
I also carry a small zip lock snack size plastic bag with one or two of my favorite brand of large condoms and a tiny packet of surgical grade medical lubrication if needed.

And yes, always commando!

I'm with IR; take the fob (plus 2 keys) on a snap clip that goes on my belt loop. For dances, I set my keys, phone and drink on a table or floor; double check before I leave. But sitting at a table out in the open, I don't set anything on the table.

I’ll give you some great advice that was given to me years ago.

“Buy low, sell high”

You can’t lose that way.

"How do you handle your cash/cards?"
I don't do anything different, though I know I've inadvertently handed Club Desire waitresses my health insurance card stuck to my silver card, before. I know I won't be tempted to use the ATM or my credit card, so that's moot. You shouldn't be in this hobby at all if you can't control your dick or wallet.

"What kind of clothing do you recommend in the club?"
I just stay comfortable and soft. I don't go commando and I'm not one of those weird people who asks what pants are easiest to cum in. New jeans are rough on their skin, but they love either old and soft jeans, soft khakis, or corduroys.

"How do you handle freshening up your breath when out at the club?"
Don't just brush your teeth, clean your tongue, and floss too. Particles in your teeth mess up your breath. Restroom trolls often have breath mints too.

"How do you handle keeping your keys safe when going out to the club?"
Nothing different.

My advice would be walk away now. Find a good Civie, jerk off or look at porn ( but not too much) if ya have to.
Otherwise you’re gonna be 60 or 70 years old looking at this same website.
Also find a good hobby, save a regular portion of your money and always wear comfortable shoes.

Skin to skin or it ain't going in.

I have a feeling OP will repeat stupid questions ad nauseum....

Only bring money you can afford to spend. Zipped pockets or carry a bag.

Pants or shorts with zipped pockets. It keeps whatever safe. Athletic clothes. Something comfortable.

Carry breath mints.

I don't agree with Puddy's politics, but I cannot deny is absolute wisdom with this line:

You shouldn't be in this hobby at all if you can't control your dick or wallet.

If you're worried about having money in your pocket or access to credit cards causing you to over spend at the club. The answer isn't to only bring what you can spend. The answer is to stay the fuck away from the strip club.

I think it's already been mentioned, but I'll reiterate to consider keeping your tipping money (small bills) separated from your dance money (larger bills). When I'm going to retrieve some singles for buying a drink or tipping, I don't want there to be any chance that a $100 bill gets lost in the shuffle. Also, I like to stay in kind of a constant state of awareness of whatever pocket has my larger bills, and also whatever pocket has my phone and my keys. Yes, that does take a little bit of extra mental energy, but on balance I can actually feel more relaxed by always being aware that my essential items are safe...

Now, exactly where to put all of these various items depends on your personal preferences, and also on whatever pockets or other storage that you have available to you. Obviously, having pockets that objects can't easily slide out of might be preferable, but again, awareness can help make sure you don't lose something critical...
