A generic policy describes a generic venue. Yours should reflect your hours, your layout, your clientele and the situations your team actually encounters.
If a section describes something you do not do, take it out. If your team handles something the policy is silent on, add it.
Most of the value sits in a handful of concrete procedures.
A policy becomes real when staff have practised it. Short, regular conversations work better than an annual briefing nobody remembers, which is the reason our huddle material exists.
Record the training: what was covered, when, and who was there.
Set a date each year to read the policy against how the venue is actually operating, and review it after any significant incident or change of hours, layout or clientele.
Note the review date on the document. A policy dated four years ago says something on its own.
Your policy should never promise less than your licence conditions require. Read the two side by side when either changes.
