This made me laugh a bit. I have been in so many spas where girls speak little to NO english at all beyond the basic words needed to do the massage. And I have never failed to receive the service I was there for.
When it comes to spas, the girls know what to do, and when to do it. They do not require direction, and you should only need to be told, "face down please" and "turn over please" and "where massage more?".
