I had that happen to me once there, 3 times on one visit. Started with one, then I guess her 'appointment' arrived that was late. Mamsan took over 10 minutes into the massage and it was going great. Then she leans over and whispers something that I later realized was 'other girls turn', so another girl came in because I guess she was finished with her last one and was up next. It was ok, but there was never a sense of continuity as each girl kind of assumed where the other girl left off.
