Two extra people arrive at eight, know nothing about the room, and are working the busiest night of the week. What they cannot know, what that costs in practice, and the twenty minutes that changes the whole shift.

Two people arrive at eight on Saturday. They have done this job before, somewhere else, and they will do it somewhere else next week. Tonight they are working your busiest room and nobody has told them anything.

The booking was made to solve a staffing gap. Whether it does depends almost entirely on the twenty minutes after they walk in, and most venues spend those twenty minutes doing something else.

⚠️ What this page cannot tell you

⛔ How agency and temporary staff must be engaged, what you may ask of them, who is responsible for what, and how any of it is recorded are employment and contract questions. They differ by country, by agency, and by the arrangement.

⭕ Take that to your employment adviser and to whatever agreement you have with the agency. What follows is only about the shift itself.

What they cannot know

None of this is about ability. Somebody who is excellent elsewhere is blind here for reasons nobody wrote down.

Where things are

⇒ Not the bar — the spare glasses, the second ice well, the till that always jams, the door that sticks. Every venue has twenty of these and none are written anywhere.

Who to ask

⚠️ On a busy floor, the difference between a good agency shift and a bad one is whether they know which person to interrupt. Without that, they either guess or stop.

⇒ The Person Everyone Asks First

What the venue says yes and no to

Comps ／ card minimums ／ substitutions ／ whether you split a bill

⇒ These are decisions, and a visitor cannot infer them. Improvised answers become your policy for that table.

⇒ The Rules You Enforce Only Sometimes

Which guests matter

⚠️ The regular who always sits at the same table, the one who tips out, the one you would rather not have. A visitor treats everybody identically, which is correct and occasionally expensive.

⇒ The Regular Who Brings Everyone

What it actually costs

The agency rate is the visible number and the smallest part.

Somebody has to carry them

⇒ For the first hours, an experienced member of your team is answering questions instead of working. That is two people producing slightly more than one, and it is not in anybody's calculation.

Errors land in the record

Wrong buttons ／ items not rung ／ tabs opened under the wrong name

⚠️ These surface at the till at three in the morning, and nobody remembers which of them belongs to whom.

⇒ The Till That Is Always Short

And the shift after

⭕ If the same person comes back, the whole cost was an investment. If a different person comes next Saturday, you pay it again every week.

The twenty minutes that changes it

Not training. A handover, of the kind you would give a colleague.

One: walk the room, not the job

⇒ Bars, tills, toilets, exits, where the spares live, where the manager stands. Five minutes, moving. Standing in an office describing it does not work.

⇒ The Fire Exit Nobody Walks

Two: name one person to ask

⭕ Not "ask anybody". A name, and that person told they have been named. This is the single highest-value minute of the twenty.

Three: the three things this venue does differently

⚠️ Every venue has three. Say them out loud. They are invisible to you and unguessable to them.

Four: the shape of the night

⇒ When it fills, when the pressure lands, when the last orders are. ⭕ Somebody who knows the shape works differently at ten than somebody who does not.

⇒ The Run Of Show For A Busy Night

Five: what to do when they do not know

⭕ "Come and find me" is a real instruction and it needs saying. Without it, the default is to guess, and guessing is how the expensive mistakes happen.

The mistake most venues make

Treating it as a shortage problem only

⇒ The booking fills the gap on the rota. ⚠️ It does not fill the gap in the room, and treating those as the same thing is why agency nights feel worse than being short-staffed.

⇒ The Shift You Can Never Fill

Booking them for the hardest shift

⚠️ Saturday is when you need cover and the worst night to learn a room. ⭕ Where you can, a first shift on a quieter night pays for itself the first time they come back.

⇒ The Slow Tuesday You Keep Open

Not asking for the same people

⇒ Most agencies will send the same person again if asked. Most venues never ask.

Letting your team decide how to treat them

⚠️ A visitor who is ignored works like a visitor. One who is introduced works like a colleague for the night. That is set by the manager in the first minute, and the team follows.

⇒ The Story Your Staff Tell New Starters

What to write down

One page, kept where it can be handed over. This is the artefact that makes the twenty minutes into two.

Where the spares are ／ the one person to ask ／ the three things we do differently
The shape of the night ／ what to do when unsure

⭕ Written once, used every time. It is also what you give a genuinely new starter.

⇒ The Training That Happens On The Floor

What to measure

One: how many shifts were agency last month

⚠️ Most venues do not know. The number is usually higher than the impression, because each booking feels like an exception.

Two: how many were the same people

⭕ This is the number that decides whether the cost is an investment or a subscription.

Three: what the tills did on those nights

⇒ Variance, voids, and time-to-close. If they cluster on agency nights, that is the handover, not the people.

⇒ The Report You Open Every Monday

What good looks like

The name test

Ask the agency person who they should go to. ⇒ A name means the handover happened. A shrug means it did not.

The spares test

Ask where the spare glasses are. ⚠️ If they do not know, they will be waiting for somebody rather than fetching.

The repeat test

Working     — you request people by name and get them
Not working — somebody different every week, and every week feels like the first

When it goes wrong, it goes wrong quietly

An agency shift rarely fails visibly. It fails as a slightly worse night that nobody attributes to anything.

Service slows without anybody stopping

⇒ Every question, every hunt for a spare, every check with somebody — thirty seconds each, forty times. ⚠️ That is twenty minutes of floor time spread so thinly that it is invisible, and it lands as guests waiting.

The regulars notice first

⚠️ Somebody who comes every week is served by a stranger who does not know their order or their table. They do not complain. They mention it to somebody, eventually.

⇒ The Guest Who Only Comes for One Person

And the record gets thinner

⇒ Notes about guests, comps, incidents — a visitor writes fewer of them because they do not know what matters here. ⭕ Telling them what to write is part of the twenty minutes.

The agency side of it

Worth saying plainly, because most venues treat the agency as a vending machine.

They will send who you ask for

⇒ Named requests are normal and usually free. ⚠️ Not asking is a decision, and it is the one most venues make by default.

Tell them what went well

⭕ Feedback in both directions changes who gets sent. A venue that never says anything gets whoever is available.

And say what the shift actually is

⚠️ "Bar staff, Saturday" and "busy late-night floor, high volume, cash and card, expect to be on your feet for eight hours" produce different people. The second one is fairer to everybody.

Building it into the rota rather than around it

Book earlier than you think

⇒ The Shift You Filled At Six

Pair, do not scatter

⭕ Two agency people on one section with one of your team beats two agency people on two sections alone. Same headcount, completely different night.

And look at why the gap exists

⚠️ Regular agency cover for the same shift every week is not a staffing solution — it is a signal about that shift, and the shift is the thing to fix.
