Panera Cares, a charitable? arm of Panera Bread, has opened at Center Plaza in Boston. You pay what you can/want to pay. They tell you the "value" of your meal and then you place the money in a bin. They do, however, have rules and in my opinion are not very sensitive about people paying less than the value. What percentage of the value do you pay? IS it right to pay less if you are not poor?
