If you no show for an appointment, you will require a deposit for booking in the future. No shows are unacceptable. I understand that emergencies arise and things happen, however please take the time to be considerate and let me know you will not be making your appointment.
I prefer a minimum of at least 2 hours when canceling your appointment, that way I have time to fill your spot. I understand that is not always possible. If you frequently cancel your appointments or cancel last minute I will likely choose not to schedule with you again in the future.
