I was actually there this past Sunday and when I walked in, Sindy (that's how she spelled it on the card I got, anyway) asked me to take a seat and wait a minute. I assumed someone else had just finished and that they were going to pull the old switcheroo where either the other guy or I would go into a separate room/bathroom while the other one sneaked in/out. That didn't happen, as the guy pretty much stepped through the curtain and I diverted my gaze. Sindy and him chitchatted briefly and she gave him a card (presumably the aforementioned card I got after the session... doesn't seem like anything special... everything's in chinese except the phone number), and he was on his way. So, yes, there's a good chance you'll run into someone else as there didn't seem to be any real concern on their part for our anonymity. I personally don't care, but I'm sure plenty of others do. But in their defense the place is tiny, so maneuverability and logistics would be tough to manage.
Anyways, everything previously mentioned is true. From what I saw there are only two stalls, both on the left, with curtains as "doors." There is another door on the right, but it seemed more like a place to sleep or rest than something they actual use for business purposes. Also a bathroom/shower combo room. When asked if I had been there before I said "No," which wasn't an issue as I received FS wihout any hesitation on her part. She actually asked me "how much?", and I was tempted to go lower than the $60 mentioned earlier but didn't feel like haggling.
Massage was so-so, and definitely a bit short on the time. Not a big deal.. as someone else mentioned... not really what I was there for, but I wouldn't go there expecting much in that regard. After the "negotiation" she only did CBJ until I was hard and then it was straight missionary. I don't monger often so I have little in the way of comparison to other providers, but if you want more details or have questions feel free to ask.
Oh, door was also $40. Not sure why someone else had paid $45.
