I also experienced the same thing with Chalani at Nirovin. I had done 3 visits. first one was very nice,with friendly attitudes. I spent there the entire one hour at my first visit.
but i am not happy at all about the subsequent 2 visits. She was not friendly as such and she wanted to send me back quickly.
for example, her attitudes are so gone so bad that in the last visit she directly told me that we shall finish quickly because now there is a tendency of MPs being raided. this happend after 15-20 minutes. what a bloody hell...i came back and will never visit her.
my recommendation is, Chalani at Nirovin is good only at the first time. After that avoid her.
