Saturday night has a way of exposing whatever you skipped on Thursday. A chipped half-pint here, a CO2 cylinder that feels lighter than it should there, and suddenly someone is driving across town for line cleaner while the first orders are coming through. The fix is unglamorous: a twenty-minute pre-weekend stock check covering the things you cannot improvise — glassware, gas, cellar chemicals and takeaway packaging. Run it in the same order every week and it stops feeling like a chore.

Start With What Actually Ran Out Last Weekend

Memory is unreliable by Friday. Keep a running list instead: a clipboard by the cellar door, a shared note on the till phone, whatever your team will actually use. Every time someone has to borrow a glass, swap a keg early or send a delivery in a cup that does not fit the lid, it goes on the list.

The best time to write it is Sunday close or Monday morning, while the evidence is still in the bins. Count the empties against what you thought you had. Check the returns crate for packaging nobody used. Then look at the shelves, not the stock sheet — paperwork drifts, and the shelf never lies.

Glassware: Count It by Type, Not by Eye

"We've got loads of glasses" usually means you have plenty of one shape and none of the ones people are drinking from. Pint tumblers move fastest, but a busy weekend also eats stems, half-pint jugs and spirit glasses that only come out for certain serves. Count each type on its own line.

• Count every shape separately and set a working minimum for each. If you normally break a dozen on a big Saturday, that number is your floor, not your target.
• Bin anything chipped. A cracked rim is a cut lip waiting to happen, and glassware with a hairline fault tends to fail mid-service when you need it most.
• Check the glasswasher before you need it. Detergent, rinse aid, salt, filters cleaned, drainage clear. A washer running cold or low on rinse aid leaves streaks that customers notice.
• Look at the chiller. Do you have space for a full run of chilled glasses, or is a keg of something else parked in there? Frosted glass loses its point if it sits warm for an hour.
• Check your emergency stash. A box of stackable tumblers kept unopened in the back saves a Saturday when a delivery is late or a tray goes over.

Gas: Weigh the Cylinders, Don't Trust the Gauge

Pressure gauges read low when a cylinder is cold, which is exactly when you look at them. A set of luggage scales tells you more in ten seconds than any dial. Weigh the cylinder, subtract the tare weight stamped on the neck, and you know what is left.

1. Weigh every connected cylinder and every spare in the rack.
2. Check spare cylinders are in date and properly capped.
3. Inspect regulators, washers and hose connections for cracks or stiffness — a leaking washer is a slow, invisible loss.
4. Confirm you have the right gas for each line: straight CO2, nitrogen or mixed gas for stouts and some keg ales, depending on how the beer was set up.
5. Keep a full spare for every gas you run. The weekend is not the time to discover your mixed-gas backup is empty.

Gas safety deserves more than a passing glance. CO2 is heavier than air and collects in low spaces such as cellars and stairwells, where it displaces oxygen without any obvious smell. Keep the cellar ventilated, follow your supplier's storage guidance, and if you have any doubt about detection, alarms or the condition of the pipework, bring in a qualified gas engineer rather than working around it. If you or your staff ever feel short of breath, dizzy or unusually drowsy in the cellar, get out and get the space checked before anyone goes back down.

Line Cleaner and Cellar Consumables

Line cleaning is the easiest job to postpone and the hardest one to catch up on. Count your stock of line cleaner, and check it is the type your supplier specified for your system rather than whatever was left over. Store it with the safety data sheets accessible, keep gloves and eye protection to hand, and dose exactly as the label instructs — stronger is not cleaner, it is just harder to rinse out.

While you are down there, check the supporting kit: keg couplers, coupler seals, cleaning brushes, the fob detector, and the drip trays. Replace worn seals rather than tightening them harder. If a beer has been pouring with a bit too much foam or a slightly flat finish, that is usually a cellar question, not a bar question.

Takeaway Packaging and the Grab Trade

Off-premise sales get busy at exactly the same moment as the bar, so treat packaging as a par level like any other. Check cups and lids match in size and brand — a lid that fits nearly is worse than no lid at all, because it fails in the customer's car. Count carriers, food containers, napkin and cutlery packs, seals and any branded sleeves you use for growlers or bottled fills.

Test one of each. Fill a cup, close it, tip it. If it weeps at the seam, you need the better stock now, not on Saturday evening.

Get the Order In Before Thursday

Most pub suppliers need weekday cut-off times for a reliable weekend delivery, and once you are inside the busy window, pallet space and driver slots fill up. Place your order early in the week, confirm the delivery window by reply, and check somebody will be on site to receive it. If storage is tight, split the order across two drops instead of building a tower of kegs in the corridor.

Keep one emergency contact for each key category — a second gas supplier, a packager who can do a same-day run, a wholesaler who keeps your glass shape. You will only use them twice a year, and both times it will be worth it.

The Friday Walkthrough

Twenty minutes on Friday morning, with a coffee, catches the rest. Do it in the same order every week: glassware counted and stocked, gas weighed, cellar cleaner out and ready, packaging by the takeaway station, deliveries ticked off against the order. Anything short goes on the list for next week, so the problem never reaches the bar.

It is not the most exciting hour of your week. It is the one that keeps Saturday from becoming a scavenger hunt.
