A venue gets judged within moments of walking in. Sticky carpet near the bar, a smell in the toilets or last night's glasses on a window ledge, and the guest has made up their mind before they order.
The trouble is timing. Most pubs and bars close late and open again by late morning, which leaves a short window to get the place back to standard. Contractors who run a generic office routine miss the jobs that matter in a venue: spill marks under stools, beer garden furniture, the back corridor to the cellar, the gaming room after a busy night.
When that window gets missed, your opening staff end up mopping instead of setting up. Duty managers start checking the cleaner's work every morning. That's time and wages you shouldn't be spending.
