Find the place where you can sit for an hour on pocket change

Somewhere near you there's supposed to be a place — a market hall, a library café, the back of a community centre — where the cheapest thing on the board buys you a seat for a full hour, nobody hovering, nobody flipping your chair. Your job is to find it, pay pocket change, and stay long enough to prove the seat is honestly yours. If everything within reach has a laminated time-limit sign, that's also a finding — just a bleaker one.
