Believe it or not, she actually saved you money. I was there a week ago. There were 2 old Asian ladies and one young Tunisian. I went for the young one. She did not look so bad. If you like having oil spread all over your back, you might like her. If you want a massage or at least some sensual touching, go elsewhere. At the beginning she told me she'll take whatever I feel like giving her. But because of my dissatisfaction of the service, I gave her what I feel is a standard tip. Tempted to give her less but I gave it to her anyway. Then she complained it wasn't enough. I had to show her the inside of my pocket to prove that I did not bring any more money with me.
Bottom line, stay away from this place. you won't get what you expect and you're expected to pay more than other places.
