Anna Brones discusses "pay-what-you-can" restaurants, which encourage diners who can't pay to do an hour of service in exchange for their meal:
With the same idea as donation only museums, pay-what-you-can restaurants are exactly that: order a meal and then decide how much you think it's worth, or give what you can afford. … [D]o people pay? Over a year ago, chain operation Panera Bread Co. and its Panera Bread Foundation opened the first Panera Cares pay what you want restaurant, and since then they have found that about 80 percent of their clientele pay the suggested amount or more.
Game developers are also putting the business model to the test.
