There are 3 HUGE signs you arr dealing with a RnT and not legit shop.

1. The pricing. RnT us ALWAYS 30-40 dollars below legit, and general guideline is about a dollar per minute. I.e 30 min for $35 45 min for $50 and 60 min for $65

2. Id they advertise a REAR entrance

3. The masseuse enter wearing fairly revealing tops, cleavage will be on display, and the outfit will not be any type of uniform. Usually legit wear uniform.

Hth.

And yes they will usually start some gentle ball teasing bear the end of massage, and will usually ask if you want anything extra, may be accompanied by the universal sign for a wank.
