Buy four Americano's at a time, get two hours wi-fi and tell the barista to give the three extra drinks to their next three customers. You get your wi-fi, limit your caffeine intake, and help the shop generate goodwill with its customers, which in turn generates goodwill of the shop towards you. If you're gonna be a hobo, at least try and be classy about it.
