I've seen YMMV in reviews all the time but I think this the first time I am experiencing it. I have seen Butterfly four times so far and she never treated me like that. My only question is how did you pay 20 for GFE?, I always had to give 40. Either way, if 20 was agreed on then you should have received the extra services.
I apologize if you tried her out because of my review, strangely I feel disappointed. I don't have any ideas as to why your experience was so different, maybe she likes Asian guys.
