This guy makes $12,000 a month from one protein shake vending machine at a busy gym. The machine works like a smart blender, customers pick their flavor on the screen, pay by card or cash, and get a fresh ready to drink protein shake in under a minute. It also tracks every sale and shows live data, so the owner can manage everything from a phone. Some models even clean and refill automatically. If these machines are placed in gyms, universities, or sports centers, the income potential is huge.
