Cinema concessions equipment suppliers

Roughly half of ticket revenue leaves as film rental. None of concession revenue does, which makes this the most profitable equipment in the building per pound spent on it.

The constraint is almost never the machines. It is throughput at the counter: spend per head is lost when the queue is longer than the time before the film starts, and the fix is more service points, pre-ordering and collection — an operations and software problem that equipment alone will not solve.
