Step 1: Stock for that room

Match the room
Stock the building you're in, not the machine you own.
A gym will buy protein, electrolytes, and premium drinks at prices a warehouse would never pay. An office wants lunch-adjacent items and afternoon caffeine. Student housing runs late and buys differently at midnight than at midday. A manufacturing plant on shifts wants substantial food, fast. Build the list from the audience and the machine stops being a gamble.
- Gyms — protein, electrolytes, and premium energy brands at real margin
- Offices — lunch-adjacent items and afternoon caffeine on a weekday rhythm
- Student housing — late-night volume and price sensitivity in the same machine
- Plants and warehouses — substantial food that fits inside a short break
