Every time we go to swanky restaurants and pay hefty prices for the food we order, we often think how good it would be if we were to choose the prices ourselves. Now a unique coffee shop in Kirkland offers you this opportunity as it doesn't have any price listed on the menu.

Yes you heard it right - no prices on the menu, as customers at Terra Bite Lounge pay whatever they like, or not at all. The employees at the coffee shop are also instructed not to be biased to anyone or show any difference in their service towards those who don't pay or pay very less in the unique metal box that is placed there.

Terra Bite founder Ervin Peretz, a 37-year-old Google programmer told Seattle Times, "Does it really matter to any of our patrons ... whether they pay a dollar or three dollars or five dollars?"

Peretz has a firm belief in the fact that people are essentially good, but can be influenced by their environment. "If people see good, they'll be good."

"People want something different. They want simplicity of payment. They want to be taken to a new place, and they want to contribute to something," he added.

The experiment has been successful so far and Terra Bite claims to have served up to 80 customers per day, averaging about $3 per transaction.
