Need more info. 3rd party vending machines sometimes have cameras

edit: "The machine, provided by the vending supplier Canteen, features a touch screen and uses a camera for people to purchase coffee with a card, she said. But Carroll added that Amazon offers the coffee to employees free of charge and has no practical use for the camera. The cameras cannot capture audio, she added.

Upon discovery of the camera taking pictures, Amazon management addressed the issue with employees and immediately contacted Canteen, which sent workers to the warehouse to take a look at the machine, Carroll said. Canteen did not return messages seeking comment for this story. "

I have not seen a Canteen coffee machine but I know their typical setup has very obvious cameras and refrigerators that go into lock down in the case of a power failure.
