I have been hobbying for yrs and had been caught butt naked a few times as well as a customer and a few times while working at front desk. Never ever heard a customer got ticketed. Sometimes LE may question you just to know what the mpa was doing with you so they can issue the ticket to the girl if you answer you are having a massage. The girls need RMT lic to massage. If you answer you were just having a foot and head treatment they are okay. That's why when you look at massage rate charts at those semi legit spas you will see the wording which reads body treatment or finger puncture for massage rates. I have seen quite a few tickets issued to them which read " Failed to obtain a license" or "performing massage without license.". They bring along a uniform police officer so he can issue the ticket to the girls.
The LE usually wait outside watching until they see a few customers went in. Then the LE went in first and have the police waiting outside. They called the police officer in a bit later to print out the ticket. One time while I was working at the front desk, the LE came in pretending as a customer and asked me to see the girls . I didn't know he was LE so I told him this is not a full service sex place and we do not show girls. Only then he told me he is By law officer and showed me his batch. We have 2 customers inside at that time. They didn't bother the customers at all. Just asked a few questions to the girls, checked their IDs and gave a ticket to one girl who answered the wrong way. At one time at a different spa 2 yrs ago, the LE asked the customers in the rooms what they were doing. One customer answered he was having massage. So the girl got the ticket (she just retired recently). Another customer answered he was just having head and foot massage, so that girl got away. She was one of Hangdai's fav girl with very poor memory. .lol.
My point here is you have nothing to worry about LE if you are a customer at a semi legit spa. It's the girls and the spa owners, the LE is after. By Law are there just for business license matter for the owner and the girls.
