You need define "SAFE".
Safe from getting caugth by LE? from lock up? from breaking the law?
or
Safe from SO/wifey, knowing you getting caught?
In HK, it is not illegal for Male customer to visit WG, regardless HG, walkup, etc, except in if the WG is under age (below 16, if I recall) and gang bang in 1 for 1 apartment.
Worse is they drag u back to station for taking your statement and u be release in no time to punt another WG.
Unless you dont cooperate, they might threathen you by contacting your family/home.
Dont worry.....HK police dont give a shit about the customer. I been in this situation/raids many times.
