Incidentally, the office of IBM I worked at a decade ago had free sodas.
Of course, it was what became the "Solutions Experience Lab", so we had a smart kitchen set up with RFID readers for medicine bottles, and an oven that would keep things cold and remote operation capabilities. And the fridge was wired up to report electricity usage: when they first installed it, they found wildly varying swings in temperature and power use. Turns out, you need to put something in it as thermal mass. Sodas are good, but ice cream doesn't work because people eat it too fast. That got replaced with plain ice.
