Interpretive mechanism diagram, not an original campaign photograph.

How does it work?

Two friends encounter an unusually tall installation.
They cooperate to reach its elevated controls.
Their cooperation unlocks the two-for-one drink offer.

What is it good for?

Adapt the cooperation rule with two accessible simultaneous controls rather than requiring people to climb.

Evidence & sources

The campaign archive reports 800 drinks sold in nine hours and 1,075% more sales than a regular machine. The controlled comparison is not explained; this is not growth in total brand sales.
More about the evidence and execution

The unusually tall original is a reference, not an approved low-risk build specification.
