I thought this article in today's edition of USA Today was very interesting: Non-Profit Panera Cafe: Take what you need, pay what you can.
It would be interesting to see how this eventually works out.
Very briefly, the former CEO of Panera Cafe, Ron Shaich, "has converted a former Panera-owned restaurant in an urban area of St. Louis into a non-profit restaurant dubbed Saint Louis Bread Company Cares Cafe." The cafe serves the same menu as a standard Panera Bread Cafe but instead of facing a cash register at check-out, patrons face a donation box where they can leave the suggested price for their meal, leave more or eat without paying.
This past Sunday was the first Sunday that the free-will cafe was opened and revenues were up 20% over the previous week.
I hope that USA Today keeps us informed of what happens.
