A good night starts with a clear door brief.

Before doors open

Agree your admissions policy, licence conditions, expected numbers and who makes decisions on the night. Briefing comes before the first guest arrives.

Welcome and entry

Age checks, guest lists and searches where required. Apply the same agreed policy consistently, explaining decisions without unnecessary confrontation.

Queues and capacity

Keep entrances usable, monitor numbers and spot pressure building in queues. Work with your venue team when entry needs to slow down.

Difficult conversations

Address concerns early, use clear language and give people space to respond. The aim is to resolve problems before they disrupt the room.

Closing time

Plan departures as carefully as arrivals. Support a calm exit and stay alert to tension around the entrance as guests leave.

The handover

Record incidents and pass relevant information to your manager. Clear records help your team understand what happened and prepare for the next shift.
