Will say you Mate you should ask your money back or leave a small percentage of it with her for the 10min. But one question a dominatrix doesn't offer sex unless both consent to sex. Also Escort does offer sexual favourites on her list, but it doesn't mean she has to perform any of her service. Which you incline to feel cheated or rip off.
But NOT every clients go to meet Escort for sex. I have at least 4 booking upward in my time, met a Escort and no sex took place. I not going to go into detail why as that is confidential. But clients have a fetish and not all lead to sex or sexual activity.
But you are entitle to ask Mate, what you so desire in the company of a Escort. It then her choice to carry out what you requested. But just read her favourites list and ask them and if not happy walk away before money change hands.
Next time just meet a Escort with verified pictures and good amount of reviews. Hopefully next Lady you meet you be happy chap
and leave a good review after hopefully ! Good luck Mate
