L4Fgfe!
The key is to be fun rather than conducting the Spanish Inquisition while meeting a POT SB, that is if you intend to get laid!!! Look here (pun intended) this is really not a job interview but for you to demonstrate to her that she may indeed have some fun when with you and also as a bonus pick up some fund$. The more you conduct an interview style "date" the less likely you will get anything other than P4P which is fine if that's what you want and all that she is willing to offer.
Other than that, the less info you put other there the better. Why would you even wish to venture down the road of telling # 1 about a POT # 2 and so forth? Women tend to go more BSC than some men and I hasten to warn you that if you rub some of the less stable type the wrong way, you may suffer some BSC consequences! If you are not interested in someone, do NOT tell them to their face and just go the route of radio silence (they do this to many other SDs) or if you are a more caring Gent, just let them know via a txt communication that you are going to be looking at some other options. However, I strongly suggest that you "unshare" your private photos at the very least (if you do not show your mug on the public photos) or even block that POT SB whom you have no interest in pursuing. I block, block, block and even if I get some nasty messages, I block that too!
Now onto the POTs you are interested in:
I keep repeating myself time and time again that the narrative ought to be working toward longer term with stability and reliability on the part of both parties. Tell them that if there's connect and that you both mesh well together, you will seriously consider exclusivity. This onto itself will signal those with half a brain that she will not be the only rodeo for you at the present time.
Lastly, I would not flake on a POT, because I am a man and I do not do the sort of sh*t which they do! Very unlikely that a none P4P POT SB is going to take a roll in the sack with you right after a coffee meet but I must admit that I never do coffee meets.
Good luck.
