This also happened to me at Yulong. I had an appointment with one of the older guys (not Peter). Halfway through the guy massaging me left and a different guy came in (massage style completely different, hands were cold, and different feet with different sandals on (I saw through the face hole on the massage bed)). The new guy was also on his phone and I kept hearing text notifications go off. Both massages from both guys were equally terrible - the first guy was so rough that I woke up with back pain the next day, and the other guy was so light, it felt like he was just rubbing my skin up and down).
Also the facility was so small and dark and dingy so needless to say, I don’t need to have another massage there. Peter was always great though, so if one can book a private session with him (not at Yulong) I’m sure it would be worth it.
