Script 01 · Booking confirmed, with the policy in it
Subject: Booking confirmed — [day and time]
Hi [Client name], You’re booked in for [day and time] — should take around [how long]. If anything comes up, just give me [a few days’] notice and I’ll move it with no trouble; less than that may carry a small fee, the same as noted on your quote. See you then, [Your name]
Why it works Name the notice window now, while nothing has gone wrong. A later fee is then a term the client agreed to, not a rule you made up.
