Safety precautions for meeting a stripper OTC for a NFP activity.

So, Ive arranged a meetup with a dancer I meet at a club. We meet a few years ago, I’ve gotten maybe 30 LDs with her over about a 3 year span. She hasn’t done any extras for me. Claims to not do them at all. I’m not sure, nor does it matter to me all that much. We recently reconnected after about a years pause. ( I went to a distant club where she works now, hanged out and got a few more dances). Texting back for a few weeks now. She wants to learn how to trade stocks better. Agreed to meet at a library near my office for about an hour. To pay me back, she agreed to buy me lunch.

The meet is set for next week. I don’t have expectations, but there is a pretty good change of hooking up. Assuming she actually shows up, what kind of safety and privacy precautions should I undertake?

I’ve been using a texting app for communication
