As part of an Amstel marketing stunt, vending machine only serves beer to people who stand around doing nothing for three minutes.
Amstel Bulgaria used marketing agency Next-DC to build the machine. Anybody who wanted a beer had to stand in a designated spot, push a button to start a timer, and wait for three minutes before it would cough up a can from its precious inventory.
The machine was placed in a busy location in Sofia, the capital of Bulgaria, for 16 days. Beer-hungry patrons totaled up to 67 hours of doing nothing but waiting for a brewski. The total output was 1,344 free beers.
