Rashonda Thornton looked up at the menu on the wall, ordered a Caesar salad and dropped a $10 bill in a box. Pretty generous, considering the meal at Panera Bread Co.’s café in the St. Louis suburb of Clayton sells for less than $7.

It was a year ago that Panera converted the Clayton restaurant into a nonprofit pay-what-you-want restaurant with the idea of helping to feed the needy and raising money for charitable work. Panera founder and Chairman Ronald Shaich said the café, operated through Panera’s charitable foundation, has been a big success, largely because of people like Thornton.

“Sometimes you can give more, and sometimes you can give less,” said Thornton, a teacher’s assistant. “Today was one of my ‘more’ days.”
