I had a job about twenty years ago where at some point a sort of freelance tea lady started coming round. Basically had a van full of bacon rolls and a tea urn, and would drive up to office buildings and offer to come in and sell tea and rolls to the employees. The boss agreed, because it made his employees happier and cost him nothing. She made a killing. We got bacon rolls at our desks. It was entrepreneurship at its finest. Silicon Valley could never.
