You showed up. They didn’t. Check in first, then offer two times — keep any policy note plain, without inventing fees.
Don’t invent a fee. Only mention a policy you already told them.
Gentle check-in
Lead with care. Maybe something came up.
Hi Alex — I was there at 10 for our visit and couldn’t reach you. Everything okay? Want to pick a new time?
Offer two new times
Make it easy to rebook.
Hi Jordan — I came by for today’s appointment and nobody was home. I can do Thursday at 9 or Friday at 1 — which works?
Firm policy note
Plain. No made-up charge.
Hi Alex — I arrived for our booked time and you weren’t there. Per my booking note, a missed visit needs 24 hours’ notice when you can. Tell me two days that work and we’ll reset.
