Second Life: Coke Machine
This Coke machine is located in the Passions club, but many others can be found throughout the grid. It's functional in the sense that when activated, it produces cans of Coke, but despite the presence of life-like selection buttons, no other drinks are available. The cans are given away for free. Drinking Coke doesn't influence the character in any perceptable way (there are no character stats that play prominent roles in other games).
