Power Outage Plan for a UAE Café: What to Do in the First Hour

26 September 2026 · MidaOne

It happens at the worst possible moment — mid-morning with a queue, or at four in the afternoon in August. The lights go, the machines wind down, the till screen goes dark, and everybody looks at you. What happens over the next hour decides whether this is an inconvenience you laugh about later or a day that costs you a fridge of stock, a drawer that will not reconcile and a handful of customers who paid for drinks they never got. The difference is rarely the length of the outage. It is whether anyone had decided in advance who does what.

The first ten minutes, in order

Sequence matters more than speed here, because two of these get harder the longer you leave them. Walk it in this order:

  1. Stop the queue politely. Somebody goes to the door and says what is happening and what you can still serve. Customers forgive an outage; they do not forgive queueing for ten minutes to be told no at the front.
  2. Close every fridge and freezer door and leave them shut. The highest-value thirty seconds available to you. A closed cabinet holds cold far longer than one opened every few minutes by someone checking whether it is still cold.
  3. Write down what is unpaid. Any order taken but not rung up, any card payment mid-authorisation, any tab — on paper, with the amount, before anybody forgets. This is the note that saves tonight's cash-up.
  4. Find out whose outage it is. A tripped breaker in your own board, a fault in the building and an area-wide cut are three different problems with three different phone calls. Check your board, then the neighbours, then the landlord or mall facilities team.
  5. Note the time it went down, and the time it comes back. You will want both for the food decisions, for an insurance conversation and for the landlord.

What happens to the food, and who decides

Guessing here is expensive in both directions: bin everything and you have thrown away good stock, serve something you should not have and you have a far worse problem than a lost morning. The shape of the rule is the same everywhere, even though the numbers are not a blog's to state: there is a temperature at or below which chilled high-risk food has to be held, a colder one for frozen, and a band in the middle where bacteria multiply quickly. Your municipality or food safety authority sets all three for your emirate, and they are the only source worth relying on — get them in writing and keep them where staff can see them rather than carrying an approximate version in your head.

What that leaves open is the question you actually have at 10:40am — how long can this sit before it has to go? There is no universal answer, because it turns on the food, the cabinet and the room, and it is a decision your food safety plan should make in advance rather than one you improvise at the door of a warm fridge. Get the discard rule for your emirate in writing from your food safety authority or whoever wrote your HACCP plan, keep it beside the temperature log, and keep a probe thermometer that works without power so you are reading food rather than a dead cabinet display. Write off what you bin properly — the same argument as tracking café waste generally, because it is the only way you ever find out what the outage cost. Decide the priority order now too: which cabinet gets the ice, which stock moves into the coldest unit, and whether a neighbouring café would take a few crates at short notice.

Can you actually keep serving?

Most cafés can serve something through an outage, and the ones who work it out on the day serve nothing. Your espresso machine and grinder are gone — the two most power-hungry things on the counter, with no manual version. What survives: anything already brewed, anything cold, and anything you can make with hot water you already have. Cold brew is the obvious hero, made in advance and needing no power at the point of sale, which is one more argument for keeping cold brew on the menu through the summer.

Work out that short menu before you need it and keep it on a card behind the till: four or five things you can genuinely make in a dark shop, with prices. Daylight matters more than people expect — a glass frontage can trade on a bright morning and a basement unit cannot — and with extraction and air conditioning off, a kitchen becomes unworkable quickly in summer whatever the food rules would otherwise allow. Know which of those two cafés you are before it matters.

Taking money when the till is dark

A tablet or a phone runs on its own battery, so the question is not whether your device works — it is whether your point-of-sale keeps working once its connection and the shop's router have both gone. A system with a genuine offline mode keeps taking sales and syncs them when things come back; one that merely displays the menu does not. Our guide to what a POS does when the connection drops covers how to test that properly, and an outage is the harsher version of it, because the router is off too.

Cards are a separate question with a separate owner. Authorisation runs over your payment provider's network and terminal, so ask them directly what their device does with no mains power and no local network — the answer varies by provider and is not your POS vendor's to give. Then plan for the version where cards are simply unavailable: hold enough cash float to trade through it, make sure staff know they are allowed to take cash and at what point they stop, and keep a pad for anything you cannot ring up. Written orders are not a system, but they are what makes the end of the night reconcilable at all.

Write the plan on one page

Everything above fits on a single sheet, and a single sheet is the difference between a shift that copes and a shift that phones you. Put five things on it: the numbers to call in order, the short menu with prices, the fridge priority order, the discard rule your food safety plan sets, and who is allowed to decide to close. Laminate it, keep it where the closing checklist lives, and walk a new supervisor through it in their first week — the same reason your standing instructions belong in an opening and closing checklist rather than in one person's head.

Two pieces of kit earn their money before anything larger does: a small uninterruptible power supply for the router and the till device, which buys the minutes needed to finish the transactions already in flight, and a torch that lives in a known drawer. A generator is a real conversation for a café carrying a lot of refrigeration, and the honest answer depends on your unit, your lease and how often this happens to you — price it against a full stock write-off and a lost trading day rather than against nothing.

Where MidaOne fits

MidaOne has a genuine offline mode: the till keeps taking orders when the connection drops and syncs automatically once it returns, so sales made in a dark shop are still sales in your records rather than paper to key in later. It runs in a browser and as an Android and iPhone app on phones and tablets you already own, so the device in somebody's hand is the backup. Afterwards, stock you wrote off is recorded against the item with a reason and lands in the waste-by-item report, and the shift close shows cash and card expected against what was counted — so the day the power went reconciles like any other.

A till that keeps selling when everything else stops. Free for 14 days, no card required.

Frequently asked questions

How long will a café fridge stay cold without power?

It depends on the unit, how full it is, how hot the room is and how often the door is opened, so no single figure is safe to rely on. What holds in every case is that a closed door buys far more time than an open one, and that your food safety plan — not a guess on the day — should set the point at which stock is discarded.

Can I keep taking payments during a power cut?

Often yes for cash, and for a POS with a real offline mode running on a charged phone or tablet, because both work without mains power. Card payments depend on your payment provider's terminal and network rather than on your POS, so ask them what their device does with no power and no local internet.

What food has to be thrown away after an outage?

That decision belongs to your food safety plan and your municipality's requirements, which set the holding temperatures and the corrective action expected. Get the rule in writing in advance, record when the power went and came back, and check actual food temperatures with a probe rather than trusting a cabinet display.

Who should I call first when the power goes?

Check your own distribution board first, because a tripped breaker is the most common cause and the fastest fix. If your board is fine, contact your landlord or the mall facilities team, who will know whether it is the whole building, and only then the utility for your emirate.

Nobody plans for this because it feels rare, and then it happens twice in a year. The plan is not elaborate — a page of phone numbers, a short menu, a rule about the fridges and a charged device that can still take money. Write it on a quiet afternoon this week, and the next time the lights go out, the answer to the question everybody is about to ask you is already on the wall.
