Certainly! Here's an alternative version:

Life is full of surprises, and we understand that plans can change. Should you need to reschedule or cancel your appointment, kindly reach out before 2pm on the business day before your scheduled time. Any cancellations after this period will be treated as a "no show," and a 50% fee of the service cost will be incurred. I appreciate your understanding. After three no shows, a non-refundable deposit for 50% of the service amount may be required in order to book.
