Has anyone had any experience with Thai massage parlors being erotic/happy ending places? There are plenty of asian parlors in my area, but there is one Thai place that never answers the phone and hasn't had a yelp review in over a year. I suspect it might be an erotic place. There is also a new place that just opened, I found out about it by dumb luck, as they have no ads anywhere for it. I kind of took that as a good sign that maybe they are erotic. I just have no experience with Thai places though.

Not specific to TMPs or MPs in general, but many businesses will sometimes have a soft opening BEFORE any sort of Grand Opening or even just a Regular Opening.  For a restaurant it could be to make sure that the ovens, dish washers, etc. are all working spot on; if not, get them fixed! For an MP, it could be plenty of hot water; working HVAC; washer-dryer working right; etc..  
.
After all the bugs are worked out and the kinks worked in , and everything is working and the customers are happy, go ahead and advertise the real Grand Opening.

...and a good 75% offer extras.

If you ever come to London we have some great Thai Escorts who also do massage

... I see a couple of Thai woman who both are LMT but are escorts as well.  Not affiliated though with any AMP.
