USA Today -- "A Pay-what-you-want Panera in Clayton, MO is being called a success. The menu board lists "suggested funding levels," not prices. Payments go into a donation box, though the cashiers provide change and handle credit card payments.

The majority of patrons pay the "suggested funding level" or more. Statistics provided by Panera indicate that roughly 60% leave the suggested amount; 20% leave more; and 20% less. One person paid $500 for a meal, the largest single payment."
