School fairs live or die on queue management. When you add both popcorn machine hire and candy floss hire, place them on separate circuits if possible so kettle heat and floss spinners don't trip a shared breaker.
Angle the queues so they don't face each other — an L-shape or back-to-back layout keeps lines moving. One shared gazebo edge for shade stops parents from clustering in the sun between stalls.
Planning a fair? We can help you bundle hire and timing for handover.
