This could explain a few closed places.
Just thought I'd throw this out there, I've got a couple friends who are international students from China. They just flew out this morning for the Qingming Festival in China. Major traditional holiday in China on the 4th of April, but I find it hard to believe they would all be gone for that.
What's happened in the past?
For all you guys who have been at this for a while, how long has the big 6 been around? Before them was there another group of spas that did the same and got shut down similarly?
If so how long was it before the big 6 were up and running?
I'd imagine that if the organization got shut down, next man up would want to start it up again asap to get the money flowing again.
Hidden cameras in the rooms
I bet the owners started seeing an increase in BBFS and so they shut it down to prevent std's from spreading. I bet when they open back up that will not be offered anymore.
