I was at the Portland library last Tuesday looking for design books and picked up a random history of trade. It said that in the 1700s, some European coffee houses charged one penny for entry and a cup, but refills were free. I always thought the 'bottomless cup' was a modern diner thing. Has anyone else come across old coffee shop rules that seem backwards now?
But what did they do about freeloaders? That model only works if most people buy something extra, so I wonder if they had a time limit or just kicked out obvious loiterers.
That "weird coffee fact" just sounds like a different way to run a cafe. Pay a penny to get in the door and then hang out all day. It was probably more about having a place to meet and talk than the coffee itself. Calling it backwards now is a stretch, it's just a different business model for a different time. I doubt they were losing money on it. People probably bought food or something else once they were inside. It's a neat bit of trivia, but not some huge mystery.
