Vending machines were machines from which one could buy food and drinks. A vending machine in the Red Kang brainquarters of Paradise Towers contained Fizzade and the Seventh Doctor used it to get a drink, much to the amazement of the Red Kangs. After tasting it, Fire Escape declared the drink to be "ice hot". Soon, all the Red Kangs were using the vending machine and drinking Fizzade. (TV: Paradise Towers)
Barbra was a Servo-furnishing vending machine encountered by both the Tenth Doctor (PROSE: Sick Building) and Iris Wildthyme. (PROSE: The Dreadful Flap, Enter Wildthyme et al)
Razor once jokingly compared Mondasian chest units to vending machines. (TV: World Enough and Time)
