Cancellation:
If you cancel your booking/session less than 24 hours before the start time, you must still pay for the session.
Late arrival:
Your booking starts on time, although if you warn me you are going to be late I will give you 5 minutes grace period.
If you are late, particularly if you do not contact me to let me know, the amount of time you are late is deducted from your session.
