No prices: pay what you want

The Seattle Times has a story about a cafe at which

Customers pay what and when they like, or not at all — it makes no difference to the cafe employees, who are instructed not to peek when people put money in the metal lock box.”Does it really matter to any of our patrons … whether they pay a dollar or three dollars or five dollars?” said Terra Bite founder Ervin Peretz. (…)

Peretz admits that Terra Bite treads on shaky ground. He’s got to attract enough paying customers to cover the cost of those who pay less or not at all.

Peretz isn’t worried that people will abuse Terra Bite. There’s
enough money to fund the honor system, and enough honor, too, he said.

Quite a premise from which to launch a for-profit venture. Do you agree?
