Blue Phoenix Bait & Switch
There was a long back and forth on here about how Blue Phoenix will frequently bait and switch. This happens because the booker will take your reservation but the booker does not communicate with the door guy so you don't actually have a reservation. Another monger can walk in and see the woman you requested so when you arrive for your reservation they bring you to another girl.
Essentially, there is no point in making an appointment at Blue Phoenix. Just go if you're in the mood and see who is available but don't bother with making a reservation as they only pretend to accept reservations but in practice it's first come first served.
