Damn bro, sorry to hear that, might just be a bad luck for you that day or the time of the night you went(as you suggested). I've personally been to this spot 2-3 times over the past few weeks and each visit the service has been above my expectations. The girls are decent some of them have been a gem of a find and the place is cleaner then most other houses !
Just curious, you put down you visited late night on the 6th, do you remember the name of the girl you saw? I wonder if it was the same chick I saw that week.
