In the dead of night, five nights a week, a man we’ll call “Daniel” goes to work at a San Francisco Dumpster.

“At least we’re not out robbing people, breaking into cars, anything like that,” he explained as he pulled a hand-built trailer through the city alley. Actually, Daniel goes to work inside the Dumpster – harvesting bottles and cans from the drinks provided at one of the city’s well-known tech companies.

Glancing up at the office building he notes that on “20 of the floors, all these drinks are free, every day.”
