One of the nice things about life in East Asia is that most hotels offer in-room massages. They also often have health centers which will be a room with a few exercise machines attached to a sauna/spa. My wife and I have had the in-room massages several times, which we kept strictly legitimate. Once, when we lived in Manila, we were attending some function at a hotel, and afterwards decided to go for massages in the health center. We asked for a couples massage, but the room with two massage tables was occupied, so we had to go for massages in separate rooms.
So, I am enjoying my massage, and after I roll over on my back, the masseuse lets her hands start to wander. We agree on the amount for the tip. I think it was about $20, twice the amount of the standard no-frills tip. This was an upscale hotel, prices were lower elsewhere. The basic massages were paid for at the reception and the masseuses supplemented their incomes with tips from satisfied customers.
Pretty soon I am halfway to the happy ending, when there is a knock on the door and my wife calls out that she is finished with her massage.
Now the fire regulations for the health centers were that there were no locks on the massage room doors. I have been in some that didn't even have doors, just curtains. I start to panic, thinking that she is coming in, but she just says that she will wait for me in the reception area. Close call, but I motioned for the masseuse to hurry things up and in less than five minutes I was dressed and rejoined my wife. That was the last time that I took that kind of a risk.
