Hmmm. Interesting replies. Just to be clear - this is on 14th between 5th and 6th (closer to 6th). I know there are more accommodating spas further West on 14th. During my visit it was a high traffic spot with male and female clients. With the lack of noise reduction I can't see any possible way that anything more could be accomplished without tipping off the other clients, and I definitely didn't hear any tell tale noises from other cubicles. I don't usually have a problem with communication, but perhaps I'll give it another shot and make it more obvious what's wanted, although there are so many other spots to visit.
