I agree with you that you have all right to review it with your likes and dislikes and i didn't mean to jump on you personally and say you are not allowed to be disappointed about a few things.
However, as a review this is not gonna help much because other guys wont meet the same girl or wont recognize her. Also as an "how to recognize a pro" review it feels off because you mention safety measurements and even showering together (showering together is considered a GFE for cafe standards).
If you want to have control over the situation and choose a girl that seems no a "pro" i'd advice to not use the reverse nampa ones or to pay more attention in the talk room and reject girls that dont sound 100%.
I understand that maybe with the "reverse nampa" thing there are more girls that do it for fun because that way they can choose a guy who is their type. But in the other cafes you can observe the girls and how they act first, see how many girls are in the room and things like that. Plus you can choose someone who looks like your type, or try bargaining for a less pretty girl because they may do extra time or less money.
Not to talk bad about the girl you met but she could have lied about being the only girl there. If i were a guy i would like to have the situation in my own hand and pick a girl myself.
