While buying someone a drink is traditionally something done in coffee shops and bars, Pepsi’s new social vending machines are letting drinkers share soda from street corners and hotel lobbies. Once a customer buys a soda for a friend, the machine sends a personalized text or video message to the drink recipient with a code for a free soda redeemable at any other location. Drinkers can also perform “random acts of refreshment” by buying an extra soda at a specific spot so the next costumer doesn’t have to pay. Who says hydration has to be lonely?
