Listen I'm not saying they are 100% perfect, I'm saying they have great management. Even you say they are good.
If I understand, you wanted to see one girl, and were asked if you wanted a different girl, and ended up with the original girl, right? Which sounds to me like you would have been happy with either girl:
"Booked appt with Yuriko, MMS offered Emma. I said OK. Showed up and said "You wanted Yuriko right?" Yes! Wait 30 min? other customer needs more time... son of a bitch. Emma was available at the moment, so I accept "
Then you had a very good time, and even got an extra 10 minutes, right?
"(actually went over 10 min, but after all the back and forth I got in a little over the full hour). Emma is a pleaser and I'm looking forward to our next session. Definitely recommend. "
So it sounds like things worked out, which shows the high quality of the management.
