With all the Bait and Switch going on out there. I would have zero concern about costs incurred for these tactics. Not my problem.What a question... I've honestly never thought about such a situation. There has been at least one time the girl walked in to the room and I knew right away she wasn't a type I find attractive. Not really either of our faults. Like many, and understandably, she had her face hidden on the web site photos.
I'm leaning on the side of paying for the session and going through with it. Buyer Beware and Live and Learn. But the girl loses money for time and session you had booked for.
