Trust me, it does not work in your favor,normally the ladies are already busy,but calling may get you through the door at times.
Just throwing this out to you...but last minute calls, could possibly lead to a lady having back to back to possibly back appointments.
Sorry,but advanced bookings has it benefit, the lady is clean and fresh she has time to gather herself mind,body and emotionally.
How would you feel that you were her 2nd or 3rd appointment and there was like less then 10 minutes in between?:shock:
Ladies need their time between appointments, and most book in that fashion. If you happen to get lucky good for you, but in most circumstances you could be shut out.
