Most of what goes wrong on a licensed premises happens in the gaps: the manager who left before the next one arrived, the refusal nobody recorded, the group that was moved on without anyone telling the incoming shift.
A handover routine closes those gaps in a few minutes.
Keep it short and always in the same order so it survives a busy night.
Notes written during or immediately after the shift are far more useful than a reconstruction a week later. Record the time, what happened, who was involved and what was done.
This is the material that supports you at renewal, in a complaint, or in any discussion with an agency.
Keep the duty manager record where it is expected to be, current and legible. If a member of staff cannot say who the duty manager is, the record is not doing its job.
