Try this
- Separate booking, being present, payment and follow-up into explicit responsibilities.
- Confirm the access arrangements and how the person at home will report completion or an unresolved issue. Keep private entry details in an appropriate channel.
A worked example
“I can be home for the technician, but please handle the booking.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Keep access details out of general group chats when a direct channel will do.
