Cruel deception
The vending machine in the press tribune asks for a paltry 5 yuan (about $0.72) before coughing up “cold” caffeine in the form of Coke and iced tea. (“Hot” caffeine in the form of free coffee comes from machines in a lounge near the mixed zone.)
Frustratingly, the machine tends to dispense green iced tea when one presses the button for black iced tea. I’ve done this three times now and I still haven’t learned.
