The unexpected does happen in life. However, I am a small business and can be greatly affected by cancellations and no-shows. If you are unable to come please tell me at least 24 hours beforehand.
If you cancel within the 24 hours you are charged 50% of the appointment fee. If you do not turn up, you are charged 100%.
If you come for your appointment but are unable to stay the entire scheduled time, you are charged 100% of the fee.
