Pay a visit to Kirkland, WA’s Terra Bite Lounge and you can order anything you want off their menu and pay nothing. If you want, you can put money in a metal lock box (you’ll have to decide how much since they list no prices), but no one will stop you if you skip it. The brainchild of Ervin Peretz (a programmer, hence the geeky name), the coffee shop opened late last year and is averaging $3 per transaction. Peretz thinks he’ll “more than break even” when Terra Bite gets 100 patrons a day, even if some don’t pay. But social pressures are making non-payment rare — so far.
